Failed analysis stage does not properly update github CI status

[shonfeder]

When the analysis stage of the CI pipeline fails, it should fail the entire CI check, since no other jobs can proceed. But currently this is not the case, instead jobs with a failed analysis just linger as pending.

I believe this was one contributing factor to ocaml/opam-repository#26956

A current example is https://opam.ci.ocaml.org/github/ocaml/opam-repository/commit/09b8faba8678c783d4d7c8b89744d1a4f2693448/variant/(analysis) failing with
