Python version for Conda environments without Python contains incorrect information

[DonJayamanne]

Create a conda env without Python
The version information returned is invalid {"major":-1,"minor":-1,"patch":-1}

See below

This causes issues in Jupuyter extesnion as we display messages based on the version of the python environment, and -1 isn't a valid version number.
Ideally it should be undefined

I would setting the whole version property to be undefined as -1 is not a valid version.
Or have a seperate type for Non-Python environments. Such as conda environments that do not contain Python, as thats definitely possible, after all conda is not just for python, one can create environments for Java, Node.js, etc with Conda

I guess the bigger question is how do we identify Conda Environments that are not valid Python envionrments.
The current properties have no way to clearly convey this.
Hence the suggestion to have a seprate type that describes this, and that type could have a single property or the like to indicate its not a python environment.

executable.uri is undefined for such environments, will go with setting the whole version property as undefined. A single property won't do as there are other details which are relevant.
