Subject: [PATCH] Add Micromamba support (#800)

I initially tried to get Micromamba to work with Nushell by using the
script from [this
issue](https://github.com/nushell/nu_scripts/issues/578). But even after
fixing the syntax errors I couldn't activate any env.
With these modifications, Micromamba seems to be working fine.
Please note that I'm far from a Nu expert so my code might not be very
idiomatic. If that is the case please tell me so and I'll be happy to do
the necessary changes.
