On Rust code block markdown

Hello GitHub,

as you know, when you write ```rust in an input field on GitHub that supports markdown, you get colored code block highlighting for the Rust programming language.

As rs is the common abbreviation for Rust and is used for the filename extension as well, one would expect ```rs to work too, but that is not the case.

Many other languages have support for this too, like for instance Ruby and Crystal code block markdown can be initiated with both ```ruby and ```rb and both ```crystal and ```cr respectively.

I, and many other members of the Rust community, wish for this to be possible for Rust as well, with both ```rust and ```rs.

If this is not the appropriate place to inquire about this, I would appreciate it if you can guide me the correct direction.
