Make Hardcore Great Again!: Tweaks

This datapack was made for Make Hardcore Great Again! and tweaks some loot tables to make it balanced:

• Removed Totem of Undying from Evoker
• Added all types of Books to Evoker's loot (enchanted books are dropping with a really small chance)
• Added Totem of Undying to Woodland Mansion and Pillager Outpost chests (with a miniscule chance)
• Tweaked Villager trades and not nerfed them to the oblivion
• Increased chances to get a Mending book in Ancient and End Cities
