Add Installation Instructions for Windows (and everything other than Mac!?!) about kubelogin

[JohnGalt1717]

Not sure why it can't update the path automatically or if not at least prompt to do it for you? All these apps that endlessly require path updates by hand is super anoying.

[JohnGalt1717]

That's what installers are for that would also update the path automatically.

My $0.02 to install kubelogin and add it to the Windows path in one scriptlet.
(Run from Powershell)

az aks install-cli
$targetDir="$env:USERPROFILE\.azure-kubelogin"
$oldPath = [System.Environment]::GetEnvironmentVariable("Path","User")
$oldPathArray=($oldPath) -split ";"
if(-Not($oldPathArray -Contains "$targetDir")) {
    write-host "Permanently adding $targetDir to User Path"
    $newPath = "$oldPath;$targetDir" -replace ";+", ";"
    [System.Environment]::SetEnvironmentVariable("Path",$newPath,"User")
    $env:Path = [System.Environment]::GetEnvironmentVariable("Path","User"),[System.Environment]::GetEnvironmentVariable("Path","Machine") -join ";"
}
write-host "Windows paths:"
($env:Path).Replace(';',"`n")

write-host "Converting existing kubeconfig with existing azure auth provider to use kubelogin" 
kubelogin convert-kubeconfig -l azurecli

Instructions for WSL with ubuntu would be nice, with docker-desktop installed.

For Windows, the easiest way probably is to az aks install-cli

Will add this to the readme.
