Subject: [PATCH] Switch tests from `heroku/buildpacks:20` to
 `heroku/builder:20` (#693)

Since the `heroku/buildpacks:20` image is about to be deprecated,
and has been replaced by the newly added `heroku/builder:20` for
those that need to use a Heroku-20 based builder.

The build and run images used by `heroku/builder:20` are the same as
those used by `heroku/buildpacks:20` - the only differences between the
builders are the included buildpacks (which is somewhat irrelevant for
these integration tests, since the buildpack under test will be injected instead).

See:
https://github.com/heroku/builder/pull/394
