- the bin/{compile,detect,finalize,release} executables have been
wrapped in a small shim that makes sure a Ruby interpreter is
available on the PATH before exec-ing the existing buildpack
entrypoints
- works both online and offline
- currently pinned to the latest Ruby 3.1.x version available in the
Ruby Buildpack repository

Before the
cflinuxfs4stack becomes the default in CF, we will be removing therubyinterpreter from the set of installed packages. This means that the Java buildpack will need to bring its own interpreter in order to keep running on Ruby.This PR contains a small
bashshim that sits in front of each of the buildpackbin/*executables. The shim makes sure that there is an installed Ruby interpreter in a predefined location and thenexecs the equivalent Ruby entrypoint for the buildpack.The buildpack packaging and configuration have been slightly modified to allow for this to work both online and offline.
The buildpack will run with the latest Ruby 3.1.x version available in the Ruby Buildpack repository.
