Auto merge of #84886 - Xanewok:update-rls-and-rustfmt, r=Xanewok

Update RLS and Rustfmt

Closes #84537. Closes #84538.

I know there's https://github.com/rust-lang/rust/pull/82208 in progress but I'm not sure which we want to land first.

Also, I'm getting Rustfmt test failures due to inner attributes not permitted:
