build: update rules_rulst 0.49.3 -> 0.54.1

It started for me with seeing that rust_analyzer LSP does not highlight
`use prost::Message;` in bazel.rs. Actually looks like the
`@crates//:prost` dependency was not specified explicitly, and new
version of `rules_rust` catches this issue.

Build fails with below message otherwise in new `rules_rust` version if
prost is not explicitly mentioned in deps:

```
error[E0432]: unresolved import `prost`
  --> src/bazel.rs:37:5
   |
37 | use prost::Message;
   |     ^^^^^ use of undeclared crate or module `prost`
```
