remove mamba reference

[jGaboardi]

This PR removes the mamba reference in unittests.yml, which appears to be screwing up the channel priority settings resulting in a bad rtree install on Windows.

Does this essentially disable mamba? It would be great to figure out if there's an actual bug in mamba or some other way how to make it work (with mamba).

Yep, the only thing it does is remove the mamba-version: '*' keyword from conda-incubator/setup-miniconda. I think the most likely reason for the weird behavior is that we were using it incorrectly. Maybe we can get @goanpeca or @bollwyvl's opinion on this?

[jGaboardi]

Maybe I am wrong. See here.

I now see that the values acceptable in conda for channel-priority have changed since we first started using it and we had not updated. Now channel-priority: true defaults to channel-priority: flexible. We should be using channel-priority: strict.

thanks for this @jGaboardi. I'll keep an eye on what you're doing in spaghetti and try and incorporate those changes in the refactor branch also

@martinfleis and I had a major success with micromamba over the weekend that reduced total testing duration by more than half. Have a look and let me know if you'd like a PR for segregation.

[knaaptime]

awesome. if you're up for a PR against my 2.0 branch, that would be killer

(then we could close this one, actually)
