desktopCapture.getSources() returns a promise which should resolve
when capturing finishes. Internally it creates an instance of
DesktopCapturer which is responsible for resolving or rejecting
the promise.

Between the time DesktopCapturer starts capturing frames and when
it finishes, it's possible for its handle to be GC'd leading to
it never resolving.

These changes pin the instance of DesktopCapturer until it either
finishes or errors.

* docs: Update Quick Start Guide for Electron 12

With `contextIsolation` enabled by default in Electron 12, the Getting Started Guide no longer works as it is written. In order for the basic example to display values from `process.versions`, we need to add a `preload.js` to the example.

* fix: ensure child window transparency works

Windows opened via window.open and intecepted via setWindowOpenHandler
or the `new-window` event should (a) have the correct background color
and (b) that background color should be transparent if specified.

The changes in api_web_contents fix (a) and the changes in
web_contents_preferences fix (b).

Notes: Child windows with specified background colors or transpency now
work as intended

* fix: set background_color in blink prefs apply logic

* chore: update for PR comments
