Conda interpreters type not being determined

[karrtikr]

In https://github.com/Microsoft/vscode-python/blob/7c81cfcd06cdbfd91224489864ac3c9ae2c16d59/src/client/interpreter/virtualEnvs/index.ts#L50,

We determine the type of the interpreter user has set in the settings. It looks we don't bother determining whether this is a conda environment or not, which means even if the interpreter type is Conda, it's being interpreted as Unknown type.

This is something we should monitor as we roll out #12020

This is now fixed.
