fix: correct deep-remove and deep-preserve regexes

[diegomarquezp]

In this PR we fix the deep-remove and deep-preserve regexes in .OwlBot.yaml files in the monorepo by creating a temporary .OwlBot.hermetic.yaml with the corrected paths.

Why?

Because the paths specified in deep-remove-regex and deep-preserve-regex start from the library name, so if we run copy-code from inside a library, these regexes won't match any files.

What about deep-copy?

We don't need to correct the library path because copy-code sends the files from googleapis-gen (or our built temp folder in our case) to the owl-bot-staging folder. These regexes don't deal with the monorepo, they deal with the source repo, which for our case is the temp folder we build after calling generate_library. This is why deep-copy was always being "respected".

Proof

After running python generate_repo.py generate --generation-config-yaml google-cloud-java/generation_config.yaml --repository-path google-cloud-java --target-library-api-shortname merchantapi &> out, we get

@diegomarquezp We should not merge this PR before release a new version of sdk-platform-java because the common proto updates only comes in with the release.

@diegomarquezp could you use this branch and generate all libraries to check whether there are other changes (it should be no change except shopping and chat).

Sounds good. Adding a do not merge label in the meantime

sdk-platform-java has been released already. It should be ready for a review

LGTM. Once hermetic build scrips are stable, we can revert this PR and update google-cloud-java to the new format.
