fix: replace libgl1-mesa-glx with libgl1 and libglx-mesa0

libgl1-mesa-glx has been a transitional package for a while and is now obsolete from Ubuntu 23.10 and onwards.
Installing libgl1 and libglx-mesa0 instead of libgl1-mesa-glx will result in equivalent behaviour and should work on Ubuntu 18.04 and newer.
