[util] Set hideIntegratedGraphics = True for The Talos Principle 2

[artemyto]

On my system with AMD Radeon RX 6800S and AMD Radeon 680M the game picks integrated card by default.

It is literally unplayable on 680M (like much less than 1 fps).

The hideIntegratedGraphics = True option fixes the issue.

Other users also reported the problem, for example you can read about it on Proton issue tracker: ValveSoftware/Proton#7237 (comment)

I don't know the root cause of the problem, but maybe it is similar to #3725?

Also you can see many reports from people about the game selecting integrated GPU on protondb: https://www.protondb.com/app/835960.

And the game don't work well for some users with both integrated and discrete cards there, maybe those users didn't try to disable integrated graphics.

I'm generally very hesitant to do workarounds like this since it doesn't typically affect all systems, e.g. on my own laptop the game works fine as-is. Not sure why the game would default to integrated either after all the various things we've done to ensure our adapter / monitor enumeration etc matches Windows as closely as possible, so this needs some investigation.
