Update heroku/buildpacks-ruby to v7.0.0 (#683)

## heroku/ruby

### Changed

- Default Ruby version is now 3.3.7 and default bundler version is now 2.5.23 ([#408](heroku/buildpacks-ruby#408))

### Fixed

- The `docker run` command no longer requires an entrypoint when using default processes provided by `heroku/ruby` directly (and not the `heroku/procfile` buildpack) ([#404](heroku/buildpacks-ruby#404))
