* feat: added a JSON handler/fixer [wip]
Added a module that will check JSON files and give a good level of details for errors while
attempting to fix it
re https://github.com/all-contributors/all-contributors-bot/issues/102
* refactor: consolidated the fix handler
Made the fixer a bit more concise and added the fields to allow for an auto-update of the config
file (if it was changed)
* chore(package): use another `jsonlint`
* refactor(config-file): use `json-fixer`
* chore(package): bump `json-fixer` to 1.3
* chore(package): bumped `json-fixer`
