[Rust Server] Convert Rust comment to Mustache (#19595)

* [Rust Server] Convert Rust comment to Mustache

The comment about auth types supported by the generator shouldn't be
included in the generated code as it's confusing when the API doesn't
support the same auth types.

As such, we convert it from a Rust comment to a Mustache comment

* Update samples
