Nap Time - Healing Beds

This is an attempt to replace two mechanics I don't like, natural regen and sleep, with a two-birds-one-stone type of manner. It completely disables natural regen, so you won't regenerate health with full hunger. It also disables sleeping to skip the night. Instead, sleeping will let you nap, which regenerates health over time. This still costs hunger, so make sure to eat a healthy meal before naptime!

I've intentionally not had the datapack modify phantom behavior, so phantoms will spawn after 3 nights. You may disable phantoms altogether by running `/gamerule doInsomnia false`, but beware that you won't be able to get phantom membranes anymore unless you install something to change their mechanics, like (https://modrinth.com/mod/phantom-tweaks).

I also recommend a mod that allows you to sleep during the day, like (https://modrinth.com/mod/day-dream). This will allow you to nap at any time, making healing more available. This is my preferred method of play.
