Would it be possible if Dreamhost could update MediaWiki from 1.19 to to the newer update 1.22 on the One Click Installs?

I second the request. Have a couple of wikis where 1.22.x adds useful management extensions.
FWIW, it's fairly easy to install MediaWiki 1.22 via FTP. I've done it three times, and it's a bit of a bumpy ride the first time, but things do work if you are persistent and take notes.
