added ArgumentCompleter for lyrics_stat param

[sharunkumar]

This is an alternative to #428, without the issue in #429

I have tested it by invoking Install_Old_theme.bat in my test branch after replacing the urls to make sure the powershell script is running

Yes, it does seem like a problem with Invoke-Expression

Tell me how to make it work like shown in your gif from #428 , do I need to install an additional module or use a special terminal?

[sharunkumar]

install an additional module or use a special terminal

it should work out of the box on Powershell, after typing .\Install.ps1 -lyrics_stat then press tab to auto complete

Oh also if you were asking about the prompt it's oh my posh: https://ohmyposh.dev/

Oh damn, I didn't know Tab was used for that, thanks.
