Kernels with invalid Python executables get displayed & auto selected by kernel picker

A specific environment on my machine cannot install ipykernel.

Log looks like this:

Looks like it’s not even asking.

The python.exe is a some sort of redirecting exe. It’s not even a symlink.

Suggestions

• When get get list of interpreters from Python, we can check if the information is cached or not
• If cached, we get call getInterpreterDetails to get the details, if we get a response we know its valid
