Iron Lodestones Backport

Iron Lodestones Backport is a simple datapack that replaces changes the lodestone crafting recipe to use iron rather than netherite. This is a backport of a change in 1.21.5.

It is intended to support every version that contains lodestones until the vanilla change. It has been tested on these versions: ``` 20w13a 1.16 1.20.4 24w07a 24w09a 1.20.6 24w20a 24w21a 1.21 1.21.1 24w33a 1.21.4 ``` These versions were selected on account of being before or after relevant datapack changes, so it should cover all versions in between, but I can't promise 100% certainty to work with every version. Note: Some of these versions will indicate that the pack is made for a newer version of Minecraft; that is known to occur on some working versions, so it is not a sufficient indicator of failure.
