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).

Note: this isn't marked as a breaking change in the conventional commit as it is *only* breaking for C# and PHP, and Google Cloud Client Libraries for the Access Approval API have not been released in these languages yet. Anyone who previously generated libraries for these languages will see a breaking change when they regenerate though.

The nodejs_gapic_library targets were migrated to gapic-generator-typescript
which doesn't use gapic_yaml, rendering that attribute unused. Instead it uses
the proto annotations & grpc_service_config, which this change reflects.
