update build instructions for windows qt6

[r3dnasa]

building static with qt6 now works so you should prob update the build instructions

Oh they fixed qt6-static? I'll have a look and update it if it works fine on my end.

Edit: No, it's still broken here. Can you explain how you're successfully building with it?

i ran the build commands listed under qt5 static but swapped it out with qt6 and it compiled just fine

That's really weird. We were trying it in the Discord yesterday and got the same errors from improperly declared dependencies like always.
