12.0 CI is broken (and maybe in V13)

[legalsylvain]

Rational :

• [12.0][IMP] openupgrade_framework: remove FKs of obsolete tables/columns #2991 ci was green. After rebase, CI is red.

As a résult, trivial PR like #3922 are blocked

Any people intérested to investigate ?
(In the meantime, i propose to merge documentation PR to avoid to block the refactor)
