build: not relying on gax's zip archive

[suztomo]

gax-java is now part of gapic-generator-java. No need to fetch
the released zip file to get the dependencies list.

In future, we'll revisit how we maintain the dependencies to
the user of gapic-generator-java, even for self-service users.

Unclear error.

~/gapic-generator-java $ bazel run //showcase:verify_grpc succeeded in my laptop. Strange. Trying //showcase:verify_proto.

@mpeddada1 @burkedavison The failure is unclear. In another pull request, would you separate golden test and integration tests?

Also, I felt it's very strange to call Maven, which calls Bazel, which calls verify.sh. Can this be more simplified? I'm looking for something like this:

bazel ... # generate code
verify.sh # verifies the code based on golden files

When it comes to GitHub Actions, steps like this below would clarify what is it failing.

- name: Generate showcase client code
  run: bazel ...
- name: Verify the generated code against golden files
  run: verify.sh

[suztomo]

It turned out that the failure is about golden file. Not integration tests.
