Several high CVEs related to dependency com.google.protobuf:protobuf-java:3.19.2

Integrated error-prone into a project today and the dependency scanner returned the following high CVEs:

• CVE-2022-3171
• CVE-2022-3509
• CVE-2022-3510

The project uses com.google.protobuf:protobuf-java:3.19.2, so bumping to 3.19.6 will fix it. Bumping io.grpc:protoc-gen-grpc-java to 1.43.3 will keep the two synchronized.
