Python system wide install

[Josh65-2201]

Currently there doesn't seem to be a way of installing python 3 in a system wide environment. How if its already a thing can I do it.

There is currently not a switch for it in the manifest, if someone gets to it before me here is the InstallerSwitches https://docs.python.org/3/using/windows.html

You can do --override "/quiet PrependPath=1 InstallAllUsers=1, later you can do winget install python3 --scope machine

For the one adding the metadata, we need Custom: InstallAllUsers=1 and InstallLocation: TargetDir=<INSTALLPATH>

It appears the Python installer is Burn which means some of the parameters can be automated by winget-cli (Hopefully more in the future).
I cannot confirm that the --location switch works because it does not seem to work with --manifest however the --scope switch works as expected.

If you prefer Machine Wide installers you can add it to winget settings, it will then install it machine wide if there is a installer for it in the manifest.
