@adisuissa can we get this updated and merged?

I've looked into this and it turns out that buf is adding all the transitive dependencies into the lock files (in our case promethues seems to be dependent on gogo/protobuf). This shouldn't be much of an issue, as it is only a file used internally by buf (not a direct dependency of Envoy).
In any case, due to this and other reasons, I'm trying to see if we can use an alternative to buf.
I think we can close this for now, but leaving it up to you @moderation.
