[Bug]: vendored jars leak proto

[Abacn]

What happened?

Beam vendors a few dependencies (grpc, guava). These vendored dependency jars have package namespace shaded (* -> org/apache/beam/vendor/*) so it won't leak classes. However this repackage does not contain protos, as a result, it still leaks proto sources

For example, in org.apache.beam » beam-vendor-grpc-1_60_1 » 0.2:

beam-vendor-grpc-1_60_1-0.2
|-grpc
|  |-google
|  |  |-api
|  |  |  |-field_behavior.proto
...

Protobuf error

@zhumin8 created a reproducer with Protobuf Gradle plugin where it gets protoc: stdout: . stderr: sample.proto:6:52: Enum type "google.api.FieldBehavior" has no value named "IDENTIFIER" for option "google.api.field_behavior":
