Upgrade `tree-sitter-rust`

[pokey]

The latest version of tree-sitter-rust makes several changes, one of which has to do with the way that token trees within macros are parsed, which breaks our name scope within attributes (https://github.com/cursorless-dev/cursorless/blob/main/src/test/suite/fixtures/recorded/languages/rust/changeNameFine2.yml)

We should probably handle this one by constructing a text-based version of name that uses a regex to find structures of the form foo=bar, baz=bongo. We need a regex because Rust token trees don't actually have any structure. We'd probably use something like #1047 here

• Note that we will also want to tweak our condition implementation, as if_let_expression and if_while_expression are no longer special node types. We should be able to just remove the special cases for these. The if_expression[condition] and while_expression[condition] patterns should handle them properly without modification
• We should add support for let-else constructs to the branch scope type once this one is fixed as well
