Send engine devs DumpState data when games desync

[GoogleFrog]

See https://github.com/beyond-all-reason/spring/wiki/Engine-Settings-Config-File

It's now in the startscript, but was supposed to be in springsettings.cfg (file which sits next to spring.exe)

springsettings.cfg is just some file distributed with the engine, and not anything in infra code. So this should be a matter of somebody with RDP access just going there and editing the file.

I think dedicated servers use whatever is included in the default engine distribution. So the instruction would be to:

• check whether it's still needed. See whether this ticket got resolved beyond-all-reason/spring#1168
• make sure the engine version we plan to test is actually on the server via regular website upload. As of this writing the freshest engine is 105.1.1-2193-g575f94f which seems to already have been uploaded ✅
• navigate to that engine's folder (C:\Projekty\springie_spring\engine\win32/<engine>) and find springsettings.cfg there
• add DumpGameStateOnDesync = 1 to that file (as a new line in plaintext)

Desync dumps are now enabled by default in engine. beyond-all-reason/spring#1168
