Beancount syntax highlighting (zed-industries#7389)

Release Notes:

- Added syntax highlighting for [Beancount](https://beancount.github.io)

Use `Mutex` instead of a `RefCell` to acquire/release instance buffers (

zed-industries#7291)

This fixes a panic happening when releasing an instance buffer.
Releasing the buffer happens on a different thread but the borrow
checker was not catching it because the metal buffer completion handler
API doesn't have a `Send` marker on it.

Release Notes:

- N/A
