Adding PlayOnLinux in ProtonUp-Qt.

[DAM1173]

In ProtonUp-Qt v2.8.0 I miss the option to install Wine-GE into PlayOnLinux, besides other tools like Lutris and Heroic Wine. Because PlayOnLinux is still used and is included in many Linux distros, but it has an outdated custom Wine repository which doesn't contain any newer Wine versions (See left panel 'Beschikbare Wine-versies'/'Available Wine versions') . See attached images of PlayOnLinux's Wine Version Manager window below. The Wine versions 7.0.2 and 8.0.1 have been manually downloaded and installed from https://dl.winehq.org/wine-builds/.

Would you like to add PlayOnLinux as an install option in the next version of ProtonUp-Qt?

I'm not sure how many people still use PlayOnLinux (this is the first time I've heard of anyone using the project in quite a few years) but it should be possible to add I guess. The main considerations are:

• Does it support the same Wine variations as Lutris/Bottles/Heroic? (e.g. Wine-GE)
• Where are the various install locations for the Wine versions? (for each different installation method e.g. package manager, Flatpak, etc)
• What tools does it support installing and any relevant paths for these? (e.g. DXVK, vkd3d, etc)
• Is there a way to get a total game list/per-tool game list like we have for Steam/Lutris/Heroic (not sure if bottles has it)? If not we can just disable this feature (Lutris didn't have this feature until Lutris: Add Basic Games List #192)

I don't think there are any other difficulties but I guess it's a question of if supporting PlayOnLinux is worth the "effort" and maintenance "burden". If so it should probably be straightforward to add basic support for.

I don't need this, but good idea.
