Diamond Casino Heist Vehicle Paint Jobs Get a Refresh

The spawn colors for the mpheist3 vehicles have been updated.

The original colors were decent, but these new ones look much better.

Installation:

- Take the carvariations.meta file from the archive and place it in mods/update/x64/dlcpacks/mpheist3/common/data

The color choices are based on real-life references and personal preference.
