[json] Provide support for highlighting the source of the error in json files rather than highlighting the entire file

In VSCode, I have a RunConfigurationSchema.json file and a runconfig.json file open. When I edit my runconfig.json file and I make an invalid change to a parameter (as seen for the 'framework' parameter in the picture attached); all the lines in the json file are highlighted and underlined with green squiggly lines. It is difficult to decipher where the actual error is stemming from unless the user hovers specifically over the parameter containing the error. Can we instead highlight the line that contains the error only?
