default AnnotationUsage put(String key, Number numberValue) {
        return put(key, Value.ofNumber(numberValue));
    }
Use the specified key-value pair when referencing the annotation. If you
only want to show a single value without any key, consider using the
{@link #set(Value)} method.
<p>
This method works like {@link #put(String, Value)} except that the type
of the value is automatically determined as a {@link NumberValue}.

@param key         the key
@param numberValue the value
@return            a reference to this model
