[Fix] WINEPREFIX ignored when using GPTK

[SB2DD]

Just a quick fix to bug #3026. Without this fix, WINEPREFIX isn't set in the environment variables in the launch options, and therefore GPTK uses the user's default wine prefix (in my case ~/.wine). I doubt this fix is crazy perfect, but it's simple and it works!

Tested using Heroic latest on macOS 14.0 with Satisfactory Early Access. (The game is now using the right prefix's save files!)

Well, I'm confused as to why it's so angry about syntax: the 2 lines right over my commit are quite almost the same...

I think this PR should be ready for review, but I don't have the permissions to do so. (Add the tags and the reviewers)

one thing I'm worried about this is that if someone has a game already running using the wrong .wine prefix, this will break that because it will set the correct prefix (maybe losing saves for example)

I'm not sure what's the best way to handle that (we should keep the wrong prefix for current installations and have this fix for new installations, but the launch command doesn't know about that)

This would be dirty, but maybe at the next update, on first opening of the launcher, it could force the wine prefix of all GPTK games to the default wine prefix... 🤷‍♂️

That is not ideal as well since some games might already be working fine on the .wine prefix and also some people might lose their saves. Not lose, they will be there, but 99% of people will think that Heroic has erased them.

So, for now, lets keep as it is and if people come to discord we know how to proper explain the issue to them.

Thanks for the fix ⚔️

Nice, happy I could help! I think you could also close #3026, as the issue should now be fixed.
