I also removed CI_M1.yml. I did the same thing for Krylov.jl, QRMumps.jl and MUMPS.jl because we can use CirrusCI now.
We should only keep CI_M1.yml when we need to install some external dependencies such as HSL solvers.

@geoffroyleconte Should we keep the three versions of LDLFactorizations.jl in the Project.toml or just the last one?

I think we can leave it as it is (or maybe ^0.9 if you prefer).

Thanks Geoffroy! I dropped versions < 0.9.
