Update to Minecraft 1.21.5

This is the first stable release for Minecraft 1.21.5. It includes a few new features from Thermoo 4.4 and 5.3 as well that are meant to provide greater flexibility and depth.

• Updated to Minecraft 1.21.5
• Removed all deprecated APIs, including the EnvironmentController, TemperatureConverter, and some methods of ConfiguredTemperatureEffect, and TemperatureEffects.
• Many classes such as EnvironmentCommand and TemperatureCommand classes were made final, and all static only now have a private constructor. This is technically a breaking change, though unlikely to affect anyone.
• Updated game tests to use new framework
• Replaced the canFreeze and canOverheat Kotlin temperature aware function extensions with canBeCold and canBeWarm to fix a conflict with the method Entity#canFreeze.
• Environment Heat and Frost Resistance can now accept negative values. A negative environment resistance now provides a random chance of doubling a temperature decrease from an environmental source.
• Added a priority field to the environment definition. This is used to sort the order that environment providers are applied to a biome during a lookup.
• Implementation detail only: environment providers are now stored as a field of the Biome class, this should allow for slightly faster lookup times.
