Subject: [PATCH] Switch back to using `heroku/procfile` from the builder in
 tests

The `heroku/builder:22` builder image will now only ever contain one
version of the `heroku/procfile` CNB, after:
https://github.com/heroku/buildpacks-jvm/pull/608
https://github.com/heroku/buildpacks-nodejs/pull/696

As such, we no longer need to use a manual Docker Hub URL to avoid
the "multiple versions of this buildpack exist in the builder image"
error.
