1.19 Support

[Greaper88]

I've decided to update this to 1.18, and plan to maintain my own branch of the pack with published releases, at least until such time the original author decides to resume maintaining the pack. I'm not nearly as good with datapacks as the author, but I do my best.

Update: I am also doing updates for the snapshot releases as I have time to do so.
