Netherite Without Templates

Fixed some 1.20 recipes that wouldn't work due to an oversight in the json files, including for the mod support.

Removed the netherite horse armor, netherite nautilus armor, and netherite spear recipe files from the 1.21.9-1.21.10 folder since they kinda didn't exist then.

Reduced the size of a lot of files.

Moved the main files into the default "data" folder, so specific versions only have their own files when things change, such as "chain" changing to "iron_chain" in 1.21.9, and diamond spears being added to bastion treasure loot chests in 1.21.11.

Changed the name to "Netherite Without Templates" to make it less confusing.

Changed the flavor text to "No Template? No Problem!"

Up to date with 26.1-rc2, which is the same format as the prior snapshot.
