Eric Anderson 1551cc7403 Upgrade Protobuf Java to 3.22.3 (aka 22.3) The version used by protoc-gen-grpc-java will be upgraded separately, because of large C++ build changes necessary. But that won't impact users at all. We are upgrading to protoc 22.3; only the grpc plugin is not upgraded. Bazel is upgraded for both Java and C++.		2023-04-17 13:16:20 -07:00
