Mmm, good point. Marc-André's the one who's been doing the work
here, so I'm happy to leave it up to him if he thinks retaining
the fallback is the best approach.

If you make the docs/conf.py raise an error if the theme is missing,
then the existing docs/meson.build "does sphinx work?" test will
disable the docs build. (You would want to improve the error message
to note that the problem might be missing theme, though.)
