Added garuda-update remote commands
The garuda-update wiki page was missing the
garuda-update remote <verb>
functionality of garuda-update thus I decided to create this merge request for the same.
Things I couldn't achieve,
I wanted to edit the side bar of wiki so that garuda-update wiki page appears under the First steps
section just below After Installation/Garuda apps
so that the newbs could easily locate it and understand that we encourage the use of garuda-update but couldn't find any way to do that with this static output of wikijs.
