Remove rust-analyzer-compat ci check (#315)

### What

Remove rust-analyzer-compat ci check.

### Why

We added this when we seemed to be frequently breaking rust-analyzer which slowed down dev envs for devs. But it's been more than 1 year since I've seen anything break rust-analyzer. RA continues to get better, and I don't think we need to keep running this check. There have been at times problems with the check, although not frequent, it's part of our process that isn't serving the need it was created for any longer.
