Request: detect newer Powershell installs

[mikemaccana]

For other new people, it would be cool if Fluent Terminal detected new Powershell releases.

They're normally installed into:

C:\Program Files\PowerShell\6\pwsh.exe

+please 🙂

This is somewhat connected with #263 We should add some general detection logic for the preinstalled profiles

Also for previews - C:\Program Files\PowerShell\(someVersion)\pwsh.exe. Eg, 6-preview or whatever.

For releases from Microsoft Store, it is at %LOCALAPPDATA%\Microsoft\WindowsApps\pwsh.exe
