chore: updates protobuf dependency

[jayhof]

Fixes #289

[jayhof]

I think I also have to upgrade some other dependencies like fs2PubSub. I'll try that and provide updates here, if someone has any hints please feel free to let me know 😉

Upgrading protobuf resulted in the stream constantly resetting identifiable by this DEBUG lvl message:
[grpc-default-worker-ELG-1-4] DEBUG io.grpc.netty.shaded.io.grpc.netty.NettyClientHandler - [id: 0xfe6a3893, L:/10.176.0.194:42942 - R:pubsub.googleapis.com/142.250.186.106:443] OUTBOUND RST_STREAM: streamId=369 errorCode=8

I ended up downgrading protobuf to 3.25.3, a version before their breaking release described in this commit: protocolbuffers/protobuf@df8a11e

This seems to work once deployed to GCP with pubsub, if anyone wants to try here's the docker images:

Downgrading is probably not what we want here but someone more familiar with the stack will have to take care of it so I'm going to close my PR.
