Update Protobof version to 4.33.2 (latest)

@siri-varma I am worried about doing this, because we the grpc netty libraries also depend on Protobuf. As far as I remember we upgraded to the version that was aligned with Spring Boot and the versions used by the Spring Boot Otel instrumentation that also uses GRPC. I wouldn't upgrade this unless we are also upgrading those dependencies. Can you check which dependencies depend on protobuf by running mvn dependency:tree

[salaboy]

I don't think I can approve this unless we check which transitive dependencies also depend on this.
