Chest Boat Patch

I've been meaning to get around to this for a while. I kinda had to relearn how Fabric handles client and server code. Found out the hard way that they finally separated the main and client directories/classes finally. Anyway, here are the changes:

• Updated to support 1.21 and above.
• Fixed the version string substitution in fabric.mod.json
• Moved all code from main to client.

• Add support for 1.20.1

• Updated to 1.20

This release is only compatible with 1.20 and above due to changes in Minecraft.

• Updated to Minecraft 1.19.4
  • Due to recent code changes by Mojang, this release is not compatible with versions prior to 1.19.4
• Updated Fabric loader version to 0.14.17

• Fixed #1
  • Set target and built with JDK version 17

• Added support for 1.19.3

• The mod only changes the mountKeyPressed variable if the key is pressed, instead of at the end of every tick.
