Some modules do not have the generated samples directory copied over from googleapis-gen. For instance see java-container in googleapis-gen: https://github.com/googleapis/googleapis-gen/commit/73ec3348990fb308d3b600a0940ae852d47247ee, but the same PR in the monorepo doesn't contain the samples/snippets/generated directory: googleapis/java-container#848

This is because some modules are missing the correct copy/remove regexes in their .OwlBot.yaml files.

deep-remove-regex:

• "/samples/snippets/generated"

deep-copy-regex:

• source: "/google/cloud/${module_name}/(v.)/.-java/samples/snippets/generated"
  dest: "/owl-bot-staging/${module_name}/$1/samples/snippets/generated"

See https://github.com/google-cloud-java/blob/main/java-apigee-registry/.OwlBot.yaml as an example of a correct file.

The new client generation file should get updated as well: https://github.com/googleapis/google-cloud-java/blob/main/generation/new_client/templates/owlbot.yaml.monorepo.j2
