[Java] gRPC not available on M1

[asfimport]

When building on M1 gRPC is not found. It can be manually downloaded and installed:

mvn install:install-file -DgroupId=io.grpc -DartifactId=protoc-gen-grpc-java -Dversion=1.41.0 -Dclassifier=osx-aarch_64 -Dpackaging=exe -Dfile=/Users/<user>/Downloads/protoc-gen-grpc-java-1.41.0-osx-x86_64.exe

But perhaps that could be fixed as suggested here: grpc/grpc-java#7690

I think this is stale; we build and test on macOS ARM64 now.
