[Pkg-rust-maintainers] Bug#1103833: rust-protobuf: CVE-2024-7254

[NoisyCoil]

I decoupled handlebars from the rest and filed [1] to also decouple 
prometheus: erbium (its only (transitive) reverse dependency 
application) doesn't use protobuf's functionality. This however is not a 
small change, so it needs consensus from the team (hence the MR). Pros 
and cons are detailed in [1].
