Add a user-friendly message on how to fix jsonlint failures

What does this MR do and why?

As outlined in !98068 (comment 1244327608) the jsonlint output is not the most user-friendly. This MR enhances the lint-json.sh script to output a suggestion on how to fix the problematic files.

Screenshots or screen recordings

  EXECUTE > jsonlint
package.json is not pretty

Some of the JSON files are not pretty-printed, you can run:
        scripts/lint-json -f $(git diff --name-only master... | grep \\.json)
to fix them

How to set up and validate locally

1. Create a commit that changes any JSON file in the repository in a way that's not pretty-printed
2. bundle exec lefthook run pre-push
