rls no longer builds after rust-lang/rust#61027

[rust-highfive]

Hello, this is your friendly neighborhood mergebot.
After merging PR #61027, 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 @Centril, do you think you would have time to do the follow-up work?
If so, that would be great!

cc @Centril, the PR reviewer, and @rust-lang/compiler -- nominating for prioritization.

in the absence of a log describing the problem, I'm currently guessing that this is possibly due to #59742. (100% guess.)

My understanding is that this sort of breakage is not a "drop everything" kind of problem, but something we do want to resolve in due course.

triage: P-medium; removing nomination. Assigning to self to try to keep track of it. But I suspect @Xanewok will be best suited to do the actual work.

(its also possible that this was fixed but no one linked this issue from the PR that fixed it...)

Clippy-related breakage, I believe this was specific instance was fixed in #61044.
