build: drop shortened URL from lint-commit-message

The shortened link to the commit message guidelines no longer works
after they were moved from `docs/guides` to `docs/contributing`. Now
that `core-validate-commit` outputs an error message pointing to the
full URL of the commit message guidelines on failure we no longer need
to include the URL (shortened or otherwise) in the workflow title.
