Add support for conda env create -f environment.json

[swaldhoer]

Description

Add support for

conda env create -f environment.json

The whole environment thing was very yaml specific (I mean obviously, it was the only supported format 😅) and for sure it will be staying like that, so tried to implement everything in a backwards compatible manner.

I add documentation (again the whole docs are very yaml centric), so I just added it a few points, so that one is able to create an environment.json file and create the environment from that environment.json file.

I added some basic tests, however, frankly speaking I am not sure whether these are sufficient.

Fix #12942
