steamdetection: stop blacklisting Proton 11

The wineboot -u deadlock workaround (waitforexitandrun + ntsync env nudge)
already lives in prefixsetuprunner, so the catch-all Proton 11 skip in
findSteamProtons is no longer needed. Users on stock Proton 11 are now
selectable alongside Proton 10 / Experimental / GE-Proton.
