Add mamba option to miniconda

[Shotgunosine]

We're having trouble getting conda to install pandas in a timely fashion over in the freesurfer bids app: bids-apps/freesurfer#67

Adding an option to use the mamba solver with miniconda would solve that for us.

that's a great feature :) thank you for the pull request!

Thanks, @stebo85, any ideas why the linters check is failing? Something about not being able to access the user site-packages directory? Seems like the same error as #561.

@stebo85
Do you think that we want to add a test of installing conda on the list of all the "containers" we test?
It feels a bit silly to just install conda with no packages but if something start failing with a given distro, at least we may hear about it.

[stebo85]

yes, that's a good idea. I haven't seen any issues with miniconda / mamba across different base systems, but a test for it would be nice
