[micromamba] Using --json for `micromamba create` eats up all error messages

[romain-intel]

If there is an error in creating an environment and you use the --json option, the error is not reported back. Worse, the returned JSON says "success": true. micromamba does return a non-zero code but any error is gobbled up.

Same problem with the json here. In my case if a package is not available in a list of packages, while conda returns (among others infos) the type of error and the name of the bad package like this:

conda install --json bad_package 

{
 [...]
  "exception_name": "PackagesNotFoundError",
  "packages": [
    "bad_package"
  ],
}

mamba returns just the following json:

mamba install --json bad_package

{
    "success": false
}

[romain-intel]

at least the success is set to false :).

any updates on this? Thanks!
