test: update github actions CI and run tests on LTS and pre

[franckgaga]

Trying to:

• closes Update test.yml with new github actions #975 (it theoretically improves the performance of testing on CI with caching of testing dependencies)
• closes Different behavior of MIMO system construction on Julia 1.12 #987 (the part about testing on pre: it can be useful for preemptive testing and is less noisy than nightly)

Since pre is not intended for normal julia users (i.e. non-package developers), I don't think it should impact the CI badge.

@baggepinnen See above, I think it's a great improvement to be a bit less "extinguishing the fire" in the maintenance of the package XP

It seems the the failling tests on pre are legit bugs, do you agree ?

[franckgaga]

So I'm pretty sure that it's a bug in Julia 1.12, not in this package.

See JuliaLang/julia#58866

The testing on pre has to be marked an allowed failure, otherwise a low-priority issue (issues with unreleased version of julia) may block the fixing of high priority issues. Testing on unreleased versions has always been very noisy, which you just found out that even pre-releases are, and I don't want such failures to prevent merging of unrelated PRs.

[franckgaga]

That is why I added this line. The failure on pre will be ignored in the final CI results.

Note that the icons below can be misleading since there is a big red X on pre. The CI badges will still be green howeve, as far as I know.

This is an issue with GitHub actions, the allow-failure setting does not exist for now actions/runner#2347
