The explicitly specified package name is invalid since it identical
to one of the keywords in Go (e.g., "package" or "type").
Remove explicitly specifying the name, which will cause protoc-gen-go
to derive the package name from the last path segment.
If the name is not valid, it will automatically sanitize it
to produce a valid package identifier (e.g., "_package" or "_type").

In particular this applies to Java and Python microgenerators.
With this change `java_gapic_*` and `py_gapic_*` rules mean microgenerator versions. The monolith versions of the rules are named as `java_gapic_*_legacy` and `py_gapic_*_legacy` respectively.
Also change Ads BAZEL template to reflect the change in default rule names.
Also change `DO NOT OVERRIDE` comment warnings meaning (to reflect that now by default microgenerator rules are generated and the generated version must be accepted only if the API is being migrated to the microgenerator).
