Currently, any commit to React causes an internal sync since the Git
commit hash is part of the build. This creates a lot more sync commits
and noise than necessary, see:
https://github.com/facebook/react/commits/builds/facebook-www
This PR changes the version string to be a hash of the target build
files instead. This way we get a new version with any change that
actually impacts the generated files and still have a matching version
across the files.

Test plan: Ran the workflow
[successfully](https://github.com/facebook/react/actions/runs/3595185062)
Should hopefully be final tweaks! Sorry about all the noise.
Test plan: temporarily ran the workflow on this branch, verified output
in the builds/facebook-www branch is correct:
bfc0eb6cd4
This PR adds a new GitHub action to commit build artifacts for Facebook
into a new protected branch. This will later be used to setup an
automatic sync to www.
The hacky spinloop is meant to be a temporary implementation until we
can support running a script internally on top of the synced diff
(coming soon). A GitHub token is otherwise required if we want to setup
a pub/sub between cirleci and github but it's not straightforward to
provision one for our org. So this workaround should do for now since we
won't keep it around for too long.
Example of it running and creating a commit on the `builds/facebook-www`
branch:
