Today we hide kernelspecs for various reasons,
one of them being it is the same as selecting the same Python Environment.

Why not hide them:

• Users look for them and file issues
• Users think Jupyter extension does not work and cannot find the kernels

Why hide them

• Users get confused between environments and kernels
  this argument no longer holds true as we have two separate entries in kernel picker,
  One for Python Environments & another for Jupyter Kernels.
