Docs: repoquery depends requires installed or channel (#2088)

[samtygier]

The command mamba repoquery depends requires the package to already be installed in the environement. Otherwise the channel must be specified.

Closes #2088

In my test, even if the channel is specified it does not work:

docker run -it --rm mambaorg/micromamba:1.0.0 bash -c "micromamba repoquery depends -c conda-forge xtensor"

It seems like the package specified must always be installed in the environment. If it's excepted then that should be reflected in the doc more explicitly no?

[samtygier]

I am not sure if the difference between mamba and micromamba is expected, or should be considered a micromamba bug?

[hadim]

My preference would be to stick to what mamba does already: not requiring the package to be installed. Maybe both behavior should be supported and one of them behind a boolean flag? I can see usecases for both.

Thanks for submitting this PR!
micromamba's behavior is indeed a bit different. I will open an issue for that.
