I had a look at the errors. It seems to me they are mostly unrelated to the new version. Except for functoria and mirage's dune runtest failure because those keep on wanting to test cmdliner's documentation generation output.

@raphael-proust fixed functoria's and mirage's tests in #23663.

Good to go now. Thanks!

Thanks to both!
