chore(docs): add empty changeset step to actions (#6377)

- Creates a script that runs the `yarn changeset --empty` command if there are file changes. This is important to not create PRs of just empty changesets if there are no file changes.
- Run script in all docs-generation PRs
- Fix to condition in `generate-docblock` action
