[FIX] Switch to sniper runtime

[Etaash-mathamsetty]

People who recently installed steam on Linux will have only the sniper runtime installed, therefore we should switch to it by default.

Use the following Checklist if you have changed something on the Backend or Frontend:

• Tested the feature and it's working on a current and clean install.
• Tested the main App features and they are still working on a current and clean install. (Login, Install, Play, Uninstall, Move games, etc.)
• Created / Updated Tests (If necessary)
• Created / Updated documentation (If necessary)

Maybe another alternative is to detect if the sniper runtime is installed first and then switch to that?

For instance, my system still has the older scout runtime since I didn't use Steam for quite some time. So launching a Linux native game from Heroic will fail to launch if I enable the checkbox unless I download the runtime from Steam. But I'm pretty sure many other users may not have the same case as me.

Another way is to display a dialog asking the user to install sniper runtime in Steam.

Ok seems fair

The Sniper runtime only works with version 8?
Perhaps we should have a method to get all available runtimes like we do for the Wine versions.

Then, depending on the Proton version we select the correct runtime. If it does not exists, simply ignore the runtime setting.

that's going to be very hard how are we supposed to detect if a certain version of proton is proton 8? And some proton-tkg builds use soldier even on the 8.x series (I think)
I think we should just keep it simple and fall back to soldier when sniper is not found, proton isn't recommended anyway

Doesn't tool manifest indicate that?

Looks good, one small syntax thing to consider
