[FEATURE] Show the Proton/Wine version of the games installed and allow a batch update

[italoghost]

Is your feature request related to a problem? Please describe.
I would like to see the Proton/Wine version of the games that I have installed and have a way of batch update their version.

Describe the solution you'd like
ProtonUp-Qt has a feature that shows the Proton/Wine version of the games installed (be it Steam, Lutris or Heroic) and allows the user to batch update the Proton version of the games (this only works on Steam, tho). I think that ProtonPlus could copy this feature!

Describe alternatives you've considered
I currently use ProtonUp-Qt, but ProtonPlus would fit better on my Gnome environment.

I will not be available for 8 weeks sadly, but once I am back I'll make sure to implement that.
Thank you for your interest in ProtonPlus and sorry for the time it will take to add.
