GitHub Actions "tools" builder is broken

[RalfJung]

In #71173, the Azure "tools" PR builder succeeded, but the GHA "tools" builder failed twice because it considers rls and rustfmt broken, saying

Looks to me like something is wrong with the GHA builder.

This is almost certainly not spurious - rustfmt likely needs to update it's version of the autopublished rustc_session crate. I can take a look today at doing so.

[RalfJung]

Well, it works fine on the Azure runners though (and the PR landed now).

[RalfJung]

But also #71159 landed in the mean time... but when the Azure runner ran I don't think it had landed already.

[pietroalbini]

I'm pretty sure that's because GHA is using a fork of the toolstate repository in my own account, and updating the data is still broken. Let's see if it turns green once I update my fork.

[Mark-Simulacrum]

Ah, yeah, that could explain it. Both the Azure and GHA builds failed the exact same way, just GHA considered that a regression (so it failed, as we're in beta week).

[pietroalbini]

Updated the fork, let's see if it works now.

[pietroalbini]

Opened #71195 to track master failing.

After the updated fork this started working again, closing the issue.
