I'm not sure what's the best way forward. If it's only the tests that break, or
if the doc output is only affected in a minor way, obviously disabling those
tests is a reasonable option. Might be better than removing qdoc-qt5 entirely.
Bumping to RC as it is our goal to get rid of llvm 15 for trixie.
