Update to Minecraft 1.21.5

This is a first release for Minecraft 1.21.5. It is initially released as a Beta because Cardinal Components API is not yet stable, however from my testing it does seem to work fine. If you find any issues please feel free to report them to https://github.com/TheDeathlyCow/thermoo/issues.

• 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.
