Downgrade bundled Python to 3.9.13 on Windows

[justinlampley]

The current bundled version of python for windows, 3.11 alpha, does not work with the Platform IO 1.1.2 installer, so downgrade the bundled python for windows to 3.9.13.

Tested on Windows 10 and in a Windows 11 dev environment VM.

On Windows 11, there is an error when installing platformio in regards to the wheel package, but it doesn't seem to affect platform io or building the firmware and it occurs on all the versions of python I tried.

  Building wheels for collected packages: platformio
  Building wheel for platformio (setup.py): started
  Building wheel for platformio (setup.py): finished with status 'error'
  error: subprocess-exited-with-error
  
  python setup.py bdist_wheel did not run successfully.
  exit code: 1

  [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.
  Running setup.py clean for platformio
  ERROR: Failed building wheel for platformio

PlatformIO Core has been successfully installed into an isolated environment `C:\Users\User\.platformio\penv`!

I have also included a PowerShell script that creates a portable version of python, which will make it easier to change versions if we need to do so again.
