docs: programming-language: add Rust programming language section
Following the C text in the file, add a mention about the Rust
programming language, the currently supported compiler and
the edition used (similar to the "dialect" mention for C).
Similarly, add a mention about the unstable features used (similar
to the "extensions" mentions for C).
In addition, add some links to complement the information.
