Re-enable the check-style workflow, as it's back to working correctly.
Tested runner here.

And of course it doesn't work on the PR into the repo 🙃
More to come - as I've been digging at this...

Oh. It didn't fail to work.
It correctly identified a whole shitload of bad formatting since it's been disabled.

Don't know what we wanna do about that ...

Can we make it only check changed files?
If not, we should disable the most commonly flagged rules, and fix the remaining bugs immediately. Then over time, re-enable the rules again.
