Aquatic Torches for Fabric 1.21.1

This is a 1.21.1 port of Aquatic Torches (originally by [realmayus](https://modrinth.com/user/realmayus) under MIT) for everyone's convenience.  The original can be found [here](https://modrinth.com/mod/aquatic-torches/). It hasn't been updated in a year, and I really needed it for an SMP, so... The only thing I changed was making the torches use the Glow particle instead of Glow Squid Ink, because I found it too obtrusive. All the assets belong to them, that being models and textures, and I take no credit. The mod itself was recoded from scratch though.
