going to merge this in 24 hours

Thanks.

Note we changed how notarization works because the tool we were using (altool) is going to be deprecated by Apple and the actions we used are now archived and unmaintained. Fun fact: this was reported by the Anaconda team working on using our constructor improvements :)

This should be more reliable, but we need to test it in a run where the secrets are available.

So yes, let's merge to not block QA but I might need to adjust a couple details in a further PR.

Is there anything I ca do to help test this ? In particular I have a mac with an apple arm64 chip if that helps.

We need to check the notarization steps, running here napari/napari#5411

Once we have some artifacts, we can QA whether the installer throws warnings, shortcuts are created, etc. I'll ping you in the other PR once they are ready, @Carreau. Thanks!
