Due to the way PRs are merged to both master and patch branches, the size
tracking goldens for `11.2.x` have gotten slightly out of sync, causing
failures at HEAD.

This commit corrects the goldens (an increase of approximately 500 bytes).

fix(platform-browser): prevent memory leak of style nodes if shadow DOM encapsulation is used (#42005)

Prior to this change, any inserted `<style>` nodes into shadow dom trees would be retained
in memory, even after the shadow dom tree has been removed. This commit fixes the memory
leak by tracking the inserted `<style>` nodes per host element, such that removal of the
host element also releases the style nodes.

The JIT compiler has a mapping from component to the owning NgModule
and tracks whether a certain NgModule class has been verified; these
maps causes any JIT compiled component and NgModule to be retained even
if they are no longer referenced from anywhere else. This commit
switches the maps to `WeakMap` to allow garbage collecting any
components and NgModules that are no longer referenced elsewhere.

After the changes to the `lang-none` styling in #41335, code snippets marked with

```
language="none" class="code-shell"
```

were being styled with the same foreground and background colours.

It turns out that most of these ought to be marked `language="sh"`
in which case the `code-shell` style became redundant and has been
removed.

PR Close #41960

Such injectables were not appearing in the providers lists of their NgModule.
This commit updates the doc-gen to support associating these automatically.
Further, it also allows developers to mark other injectables that are provided
in an NgModule with a reference to the NgModule where they are provided.

The commit also does a refactoring of the `processNgModuleDocs` dgeni
processor code, to make it easier to maintain.

Enable a GitHub action that implements our new feature request
[process](https://github.com/angular/angular/blob/ce8e011a9f7c6bac94292d632b0cc8822f710a66/docs/GITHUB_PROCESS.md#feature-request-process).

As a prerequisite, we need to create the following labels:
- `in backlog`
- `votes required`
- `under consideration`
- `insufficient votes`

The bot will also use the existing `feature` label to identify feature
requests.

With its current configuration, we need to kick the process off
manually. We currently also have a limit, meaning the bot will process
only 50 feature requests before it exits. Additionally, now the bot will
not close issues, it'll just comment on them and if they have an
insufficient number of votes, the bot will label them with `insufficient
votes`.

On the next iteration, we can:
- Expand the limit from 50 to infinity (removing the option from the
yml file)
- Set a cron configuration to kick off the bot automatically
- Enable autoclose by setting the `close-when-no-sufficient-votes` to
`true`

We recently added a sanity check that ensures that `python` is
available for Bazel. The check relies on `/usr/bin/python` to check
if python is available w/ the correct version. The problem is
that on Windows there is no guarantee that the `/usr/bin` folder
exists, so the `ng-dev release publish` command always fails.

We fix this by just accessing the `env` binary that is also consulted
by scripts executed within Bazel actions. The `env` binary can be
assumed exist in the shell's `$PATH` and can point us to Python
as if it would be executed within Bazel.

Currently we have a common utility method for running commands
in a child process. This method pipes all stdout and stderr, but sets
the `stdin` to `inherited`. This seemed to work as expected in terms of
allowing interactive commands being executed, but it messes with the
TTY in Windows (and potentially other platforms) so that colors and
prompts no longer work properly. See attached screenshot.

We fix this by not inheriting the stdin by default; but exposing
a dedicated method for interactive commands. This results in more
readable and obvious code too, so it's worth making this change
regardless of the TTY issues.

PR Close #41945

Currently if a major release-train in the `release-candidate`/`feature-freeze`
phase becomes `latest`, we intend to set the NPM LTS dist tag for all packages
of the previous major (as the old release train in `latest` moves into LTS phase).

The logic for this exists but the release tool sets the NPM dist tag for
all packages of the new major. This means that the script might error if
a new package is part of the new major; or it could cause a deleted
package to not receive the LTS tag properly.

Some localization workflows want to use the extracted source translation
files directy back in the project as a target translation file.

The extraction process generates files that only contain "source" messages
and not "target" messages. This is actually valid for most translation formats
but currently the Angular localization process expects target translation files
to always contain target messages and will stop with an error in this case.

Now, instead of an error, the translation file loader will log a warning,
and then try to falback to a source message, only erroring if this is also
missing.
