1) Deleted the db file for repacks from xatab since there are no more problems with them
2) Added the creation of a separate prefix for LGC and WGC so as not to update the default one every time (I did it according to the example from VK Play)

I tested the code on a computer with GTX 1650 and everything worked correctly, but it remains to test on RTX 20, since there is the same Turing and the script can confuse them (although it should not)

Unfortunately for lack of a 16 series card the code was not tested

Changed yad scale to yad combobox with values 30,60,90 and 120 fps also changed disable from 0 to disabled

Added Battle Of Space Raiders autoinstall
Replaced the url for the Caliber download
Deleted try_download_caliber function
Replaced wget -O in PW_ANKAMA to try_download function

Replaced which with command -v since which is already deprecated
Replaced lsb_release -d with cat /etc/os-release since this method is more universal
Fixed a couple of typos in the PortProton installation script
