Improve numerical enum mcdoc errors

[misode]

When a number is out of range of an enum type, it should just say "expected a numerical value between 0 and 15" instead of listing all the options

Where is this definition? What's the advantage of using an enum here instead of just defining an int range in vanilla mcdoc?
