Some of values in gax-java/dependencies.properties to be updated upon a release

[suztomo]

gax-java/dependencies.properties has the versions of the libraries in this sdk-platform-java repositories. The values are not updated upon a release and thus causes discrepancies in the generated build.gradle files.

Currently the values are updated by RenovateBot after a release.

This is from @jradcliff's email "Version compatibility of GAPIC genarator output and google-cloud-shared-dependencies"

Jeff Ching shared an example configuration of src/index.ts: https://github.com/googleapis/release-please/blob/3e807972fc8d1a348cd45e32d933ada4d25d4a28/release-please-config.json#L8

Thanks @suztomo! I think they should be updated by release-please, WDYT?

[suztomo]

Yes, Release Please is the solution.

Downgrading to P3 as we can always manually update the generated gradle files, and we may remove the dependencies.properties file as part of the hermetic build project.
