language: Accept multiple values in line_comment language knob. (#6713)

This opens up a possibility of supporting multiple comment continuation
flavours in editor, e.g. doc comments for Rust (which we seize as well
in this commit). Only the first `line_comment` value is used for
Editor::ToggleComments

Fixes: https://github.com/zed-industries/zed/issues/6692

Release Notes:
- Added support for doc-comment continuations in Rust language.
