Fixup automatic publishing of `libs` crates

[Veykril]

Since the rust-lang move, we no longer automatically publish these once we bump their version. We should look into making that work again.

I can look into getting this working again. What exactly happened?

[Veykril]

Auto-publishing isn't broken in that sense. It's just that for the crates under the libs directory, we don't actually want those to be autopublished weekly like the other crates (we want them to be properly versioned only, so no ra_ap_la_arena etc). That is if we bump the actual version of a crate there, we want CI to publish that version on merge and that's it. Jonas fixed that up in a PR but I haven't checked if that actually works now.

[pksunkara]

I think the version numbers went bad because of the renaming the workflow to autopublish.

Should be working now?

Looks like this failed in https://github.com/rust-lang/rust-analyzer/actions/runs/8144079470/job/22257391219#step:5:48:

Caused by:

error: unable to publish package stdx

[Veykril]

Trying to publish stdx? 😕

[Veykril]

Oh, it is because I added stdx as a dep to xtask which we aren't excluding like we do for /crates in the workflow via sed
