Version Detector

Fixed some issues and added some stuff

Changes

• Removed Bukkit detection (I couldn't make it work)

Fixes

• Pack doesn't load on versions prior to 1.21
  • This is because the '/data/verdetect/functions' (for versions prior to 1.21) folder was missing; only '/data/verdetect/function' (for 1.21+) existed.

Additions

• Forge detection support
  • Uses the validity of the command /attribute @s forge:swim_speed get to detect Forge.
  • Stored in IsForge under VersionInfo
  • Running the function verdetect:printversion will tell you that forge has been detected
• General Mod detection
  • Currently only detects Forge, but detection for other mod-related things like Fabric (if a mod with a server-side command is installed; Fabric Loader itself doesn't add anything that can be detected)
  • Stored in IsModded under VersionInfo
