Bump Rust image to 1.84.1

Tested locally against restatedev/restate#2611:

Thanks for fixing this.

[AhmedSoliman]

Needs a rebase probably. Also best to double check with @jackkleeman in case anything is missing.

[jackkleeman]

looks fine. nb, ive been struggling to get the docker image to actually build.... it hits sigsegv :(
