[github-actions-build] Couldn't open keymap file

[nistvan86]

I was about to test win64 build at https://github.com/dethrace-labs/dethrace/actions/runs/5019323827 If I enter the configuration menu and try to change to any of the layouts the game crashes, and in the log I can see an error.

Failed to open "d:\tmp\dethrace/DATA/KEYMAP_0.TXT"Couldn't open Key Map file

This works with the same game files if I replace it with the 0.6.0 release of dethrace.
