Add GitQuery Gradle plugin for syncing .proto files

[tinder-aminghadersohi]

GitQuery makes it easier to sync .proto files. We can chose to checkin the synced files, or not. Currently, since the generated kotlin is checked in, the proto files are git ignored.
Update all modules to use it.

• conformance/lib/gitquery-proto.yml
• examples/browser-js/gitquery-proto.yml
• examples/custom-service-gen/application/gitquery-proto.yml
• examples/gradle-and-jvm/gitquery-proto.yml
• protoc-gen-kotlin/lib/gitquery-proto.yml
• runtime/gitquery-proto.yml
• pumb version of proto everywhere to 3.12.2

@garyp do the failed conformance tests look right?

[tinder-aminghadersohi]

Bumped to 3.12.3. It breaks right now, but hopefully the artifact will be released soon

[tinder-aminghadersohi]

protocolbuffers/protobuf#7600

[tinder-aminghadersohi]

proto 3.12.3 has been reverted to 3.12.2 protocolbuffers/protobuf#7632

[tinder-aminghadersohi]

@garyp this is good to go apart from the conformance tests. Can we ignore the failures? Also, we need to make sure that protoc is the same version as everything else, otherwise the Test.java will be different. Do you have any idea on how we would do that? A shell task perhaps? Granted I did update the readme to state that we need to have the right version installed so maybe that's good enough.

[tinder-aminghadersohi]

I added the failures to the ignore lists for now.

@garyp would be super cool if we could merge this

[tinder-aminghadersohi]

- GitQuery 2.0.0

[tinder-aminghadersohi]

@garyp any thoughts on this?

@tinder-aminghadersohi Sorry I haven't had time to look at this yet. Hoping to get to it soon. Regarding your question about the Test.java file, I actually ran into the same issue recently and have a fix for generating the Test.java file consistently in my other PR.

@garyp oh totally understand. Awesome that you have the Test.java fix. In the meanwhile, I'll see if there is a newer protobuf aka 3.12.3 that was(is still?) missing from maven

updated to proto 3.13.0
