Description
### Description of the bug:
In Bazel `9.0.0` (rc1, rc2), the build of all `proto_library` rules of the package `@bazel_tools//src/main/protobuf` fails because the repository `@com_github_grpc_grpc` is not visible/defined.
No problem in Bazel `8.4` and `7.7`.

Research direction
Reproduce the failure with `USE_BAZEL_VERSION=9.0.0rc2 bazel build @bazel_tools//src/main/protobuf:action_cache_proto`. Start at `@bazel_tools//src/main/protobuf` and `bazel:cc_grpc_library.bzl`, then trace why `@com_github_grpc_grpc` is unavailable. Done means the proto_library targets build successfully under Bazel 9.
