proxy: Register proxy codec
grpc-go v1.60.0 adds a new check to confirm message codecs used are
registered. We currently do not register our proxy>proto codec, so
the gRPC is frequently logging:
[core] Unsupported codec "proxy\u003eproto". Defaulting to "proto" for now. This will start to fail in future releases.There is no immediate impact from these errors, but they're quite spammy.
Add an init function to the proxy package to register the codec and
import it into internal/cli/gitaly to ensure Gitaly registers it as
well.
Closes #5819 (closed)
