Look into protobuf edition support

[mstoykov]

After #3815 is merged a few dependencies seem to have support for it.

The https://github.com/jhump/protoreflect/releases/tag/v1.16.0 says protoparse doesn't yet - which seems to be the one we care about.

I am opening this issues so that we can appropriately test and do changes once this is implemented. Or even look into it earlier.
