Confusing error message for out of bound ranges

[jeromesimeon]

Bug Report 🐛

When validating an instance value which is out of bound for numerical range e.g., range=[0,10]) the error message is confusing.

For instance considering the model:

namespace test1

concept Foo1 {
    o Integer a range=[0,10]
}

And instance:

{
    "$class": "test1.Foo1",
    "a": 15
}

The error uses the value rather than the upper bound in the message:

zsh-5.8$ ./index.js validate --model test1.cto --input test1.json
9:47:08 AM - INFO: Input is invalid
9:47:08 AM - ERROR: Validator error for field undefined test1.Foo1.a: Value is outside upper bound 15
Error: Validator error for field undefined test1.Foo1.a: Value is outside upper bound 15

Expected Behavior

A less confusing error message.
