Subject: [PATCH] Update heroku/buildpacks-ruby to v4.0.0 (#607)

## heroku/ruby

### Changed

- Default process types defined by the Ruby buildpack now use IPv6 host `::` which is equivalent of IPv4 host `0.0.0.0`. This will only affect applications that do not define a `web` process type via the `Procfile` and [Procfile Cloud Native Buildpack](https://github.com/heroku/buildpacks-procfile). Those applications must make sure to update their configuration to bind to an IPv6 host. ([#354](https://github.com/heroku/buildpacks-ruby/pull/354))

### Added

- The buildpack now warns the user when environmental variables used in running the default process are not defined. ([#307](https://github.com/heroku/buildpacks-ruby/pull/307))
