Frostiful 3.0.0 Alpha 1 for Minecraft 26.1

This is a first preview build of Frostiful for Minecraft 26.1. This early build has not yet been very thoroughly tested, and may still contain bugs, so it is released as an alpha.

I have also begun the process of migrating Frostiful's config system from Cloth Config to YACL. This initial migration only includes a very basic port of the previous config options to a new YACL-based system. However, I plan to overhaul the entire config system, essentially from scratch, to create a more powerful and useful config system. Unlike previous config system migrations for Scorchful, I do not plan to create any systems for automatic migration of user config files, and all configs will be reset! This is just simply because the scope of updates I plan to make mean that the effort required to implement such a system is not worth it for me. So, this is another reason I am releasing this as an alpha. Sorry!

Minecraft 26.1 will likely be the next major LTS version for Frostiful, replacing 1.21.1 (which will remain fixes only for the time being). so between that, and the new config system, I have decided to bump the major version of the mod to 3.0.0.
