JSON validation does not catch leading zeros

[noa-dav]

Problem

The JSON validation in the react-ace library fails to detect and raise an error when a JSON number contains a leading zero. According to the JSON specification, leading zeros are not allowed in numbers. This can result in incorrect parsing and unexpected behavior when working with JSON data.
