Remove older PowerShell Az modules

Remove-Old-Az-Modules.ps1

# Note: This doesn't always work correctly.
# might get: Uninstall-Package: No match was found for the specified search criteria and module names...
# Can remove all az.* packages (and then manually reinstall) using:
# $env:PSModulePath -split ';' | ForEach-Object { Get-ChildItem -Directory -Path (Join-Path $_ 'Az.*') | ForEach-Object { Remove-Item -LiteralPath $_.FullName -Recurse -Verbose -Force }  }
# (Which could also be updated to remove just older versions in each folder)
