CI isn't happy though 🤷‍♂️

Pa11y-ci seems to have become stale, which given it's a nodejs project is probably not a good thing and might be the cause of the issue (i.e. some incompatible dependencies after chromium/puppeteeer updates?)

Someone has forked pa11y-ci and updated dependencies / released newer versions (https://github.com/aarongoldenthal/pa11y-ci / https://www.npmjs.com/package/@aarongoldenthal/pa11y-ci) which might resolve things?

I'll try it in a branch.

Switching to the fork didn't resolve the issue, but did give a slightly more helpful error message from chromium.

ubuntu-latest has changed from being 22.04 to 24.04 between this run last being successful / not being successful (and is mentioned as a warning on the last working run of the workflow 3 weeks ago)

Explicitly using ubuntu-2204 is likely the simplest fix (until something else breaks). I'll make a change in this PR once tested separately.

CI is now passing on this workflow (but not sure pa11y is actually working & might not have done for a while, but that's a separate problem).

Thanks @ptheywood 👍

Doesn't look like the cause here but R and I don't recall seeing anywhere that uses R markdown but R is no longer bundled in 24.04 and would require explicit installation after spinning up. This might impact the Handbook though after David translated it to Quarto. I'll check and make sure that doesn't break.
