Enable testing arm64 Mac architecture in the CI.

As in the title. Shoul fix #1054

Let's get the ball rolling on this.

OK, this is working, we need somehow to skip the doc test for DeepLabCut with M1s and python=3.9. On the other hand, if we follow the numpy convention we should stop supporting python 3.9 now so maybe we don't need to do that.

But this also has the support for the intel mac which I think was only discontinued from pros two years ago or something? To be honest, I would prefer to test only on latest mac, the CI is already super bloated on my view but I think there might be a case here for the two.

How do you feel about it?

I am still using an intel mac, so I would like the tests to include it. Plus, I think they're still relatively common. I agree that the CI is a bit bloated and takes too long to pick up new jobs, but I don't think this is the place to make cuts.

but I don't think this is the place to make cuts.

This make sense.

Let's brainstorm how to improve the CI at some point.
