The R check actions are currently failing because an update to r-lib actions resulted in some quarto actions being invoked, and these have not yet been whitelisted for use in Apache repositories. We don't actually need quarto for anything in the R package; however, the action is written in such a way that even though the step is skipped, the action is still loaded (and therefore its name is checked against the whitelist).

Unrelatedly, the extended R check was failing because I forgot to copy a change from #1965 into one of the workflows that only runs once a week.
