Thanks for the patch Yordan.

Apostrophes are also used to denote lifetimes in Rust, so I'm not sure this is the right fix. They are also used for loop labels, too.

We probably need to augment rust-ts-mode--syntax-propertize where we apply the string syntax property to any char_literal nodes. It would probably be too late for emacs-29 though.
