feat(gh/actions/chromatic): require label for automatic chromatic runs (

#2368)

* feat(gh/actions/chromatic): allow running Chromatic CI manually

The Chromatic build hasn't been run since we ran out of snapshots, and it's now behind and causing a few issues with snapshots. By allowing this action to be run manually, we can use the CI to update


* fix(gh/actions/chromatic): require `chromatic` label on PR's, only run automatically on PR's
