Pin the version of the rust code generation tool

In the previous commit, the version of rust, protoc-gen-prost and so on
are not pinned. That is, the latest version is used.
This will cause unexpected CI failure for commits unrelated to rust gen.

This commit pins the version in the Dockerfile:

rust: 1.81.0
protoc-gen-prost: 0.4.0
protoc-gen-prost-crate: 0.4.1
protoc-gen-tonic: 0.4.1

The dependencies are also updated:

prost: 0.13.1 -> 0.13.2
tonic: 0.12.0 -> 0.12.1

The rust code is regenerated and the version is bumped to 1.4.0
