## Context

Recently, we put bsn in the list of "macros to not reparse as rust"
(#51353).

We have since updated tree-sitter-rust to better handle the `@"string"`,
`:"string"`, etc cases, and can un-list bsn from the special casing.

on main, the highlighting currently looks like this for `bsn` and for
`not` (represents "other macros"). Note the `:"player.bsn"` string is
re-parsed as rust tokens.

This pr, plus the tree-sitter-rust updates results in better handling by
default.
