Dragon Mounts Companion

This update is here to make the modpack not crash (because phosphor) and add small modification like corpse (because i see that i remove by error the tomstone mod) which have in common the harmonisation with the future 1.16.5 version (not out because DM3 is basically non playable in survival and nobody know when the full version will release)

A huge thank to Kingdomall, former DM2 develloper and present on the DM3 discord who understand the reason of the crashing of the modpack (because i'm not a develloper, just a dude who want to make a modpack that he has alway wanted and wanted to share it)
