Auto merge of #63282 - Xanewok:update-rls, r=nikomatsakis

Update RLS

Most importantly this includes:
* Collect file -> edition mapping after AST expansion ([#1513](https://github.com/rust-lang/rls/pull/1513)) (enabled by https://github.com/rust-lang/rust/pull/62679)
* Fix rustfmt during builds by reading edition from manifest ([#1533](https://github.com/rust-lang/rls/pull/1533))

Which fixes the annoying problem where users couldn't format via RLS while `cargo fmt` worked.

The beta cut-off is drawing near and I'd like to make sure this lands before then.
