When I enabled bazel remote caching, I also switched to running
buildifier and skylint from the package.json script, which builds them
from head. With remote caching, we do get cache hits for these, but
looking up the action inputs actually takes quite a bit of time since we
have to first fetch the remote repository, then do loading and
analysis, then read the inputs to determine the cache key.

It's more important to keep the lint job fast, so I'm reverting that
part of the change for now. We can experiment with building them from
head in a less critical repo.
