The CI failures are unrelated, good to merge.

Noteworthy are the mirage failures -- where the tests use opam-monorepo (which bundles opam), which fails since the runners use opam 2.2 now, while opam-monorepo still uses opam 2.1 - which refuese to touch metadata files of version 2.2:

# +  [ERROR] Refusing write access to /home/opam/.opam, which is more recent than this version of opam (2.2~alpha > 2.1), aborting.
# +  Fatal error: exception OpamStd.OpamSys.Exit(15)
