MAINT: Pixi maintenance

[crusaderky]

• Bump pixi to latest version
• Fix issue that causes pixi 0.58 to fail when it's called from lefthook in parallel mode. I observed the same problem sporadically with past versions too.
• Run pixi update. No noteworthy changes.
• Misc CI tweaks

Could you say a little more about this? Where does the bug seem to be?

The bug in xpx CI, and what I would argue is a missing feature in pixi, is that every time you call pixi run pixi deletes and recreates some files in the environment, even if at the end of it nothing changed.
So if you run pixi run -e lint <some task> many times in parallel, like lefthook does in main, you trigger a race condition among the multiple pixi processes, which causes them to fail, because they all delete and recreate some files even if you just entered the lint environment with pixi run -e lint lint, so in theory there should be nothing to do.

Interesting. @Hofer-Julian do you know if there is an open issue for this?

Pixi's CI itself is still using this lefthook setup, so maybe there is another difference that means this isn't hit over there? What are the files created/deleted?

The disadvantage is that the duplication of lint task definitions increases maintenance burden a little.

[Hofer-Julian]

Yeah, there's this issue. Tbh I was already wondering why we don't seem to hit it with our lefthook setup:

prefix-dev/pixi#1482

[lucascolley]

Haha, I already gave it a +1 😅

[Hofer-Julian]

Maybe we should add --frozen for now? I guess this would at least avoid this problem for now

[crusaderky]

Changed to --frozen; it seems to do the job

thanks Guido, much appreciated!
