`rls` no longer builds after rust-lang/rust#66879

[rust-highfive]

Hello, this is your friendly neighborhood mergebot.
After merging PR #66879, I observed that the tool rls no longer builds.
A follow-up PR to the repository https://github.com/rust-lang/rls is needed to fix the fallout.

cc @RalfJung, do you think you would have time to do the follow-up work?
If so, that would be great!

cc @RalfJung, the PR reviewer, and nominating for compiler team prioritization.

I'm not sure but this is possibly blocked on fixing rustfmt: rust-lang/rustfmt#3903

[pnkfelix]

triage: P-medium, removing nomination.

Ping, is anyone working on this?

From rust-lang/rustfmt#3903 (comment):

I do not think this is blocking the broken RLS as AFAIK RLS does not directly depend on rustc-ap-* crates.

Sorry for that, somehow I was sure I addressed this 😲 Just opened #67198

@Xanewok no worries, thanks for the quick response :)
