* Auto-sync Gemfile.saas.lock on Dependabot PRs

Dependabot can't update custom-named Gemfiles, so Gemfile.saas.lock
drifts whenever it bumps shared gems in Gemfile.lock.

Add `bin/bundle-drift forward` to push oss lockfile changes into the
saas lockfile (the reverse of `correct`), and a GitHub Actions workflow
that runs it automatically on Dependabot bundler branches.

* Update brakeman ignore fingerprint for 8.0.1

Brakeman 8.0.1 changed how it computes warning fingerprints, so the
existing ignore entry for the safe_constantize warning in Notifier
became obsolete. Update to the new fingerprint.
