rust: Add highlight selector for doc comments (#15384)

## Release Notes:

- Added ability to style doc comments in Rust separately with
`comment.doc`
([#15322](https://github.com/zed-industries/zed/issues/15322)).


Just required adding another query to the highlights.scm file. Took
inspiration from the tree-sitter-rust repository
[here](https://github.com/tree-sitter/tree-sitter-rust/blob/master/queries/highlights.scm)

#### Doc comments customized in the theme are working now:
