feat: bake gapic-generator-java into the hermetic build docker image (#…
…3067) Makes the gapic-generator-java jar a prepared binary in the Docker image whose location is now assumed by the scripts. Developers need now to prepare this well-know location (specified in `library_generation/DEVELOPMENT.md`. --------- Co-authored-by: Blake Li <[email protected]> Co-authored-by: Joe Wang <[email protected]>
