chore: added linter for JSON files

[PKulkoRaccoonGang]

Description

With the advent of design tokens, a large number of new JSON files have appeared in Paragon. This PR provides an extended configuration of the JSON file linter, including formatting, checking for duplicate keys, etc.

How to test

1. Make some mistakes in formatting design tokens (JSON files)
2. Run npm run lint - linter errors will be displayed at the terminal
3. Run npm run lint:fix - linter errors will be fixed automatically

Overall this LGTM! I am curious as to if we want to go the "lint everthing unless we ignore it" route or if we'd rather update the files: ['**/*.json'], in .eslintrc.js to be more specific.

I'm happy with this as-is though!

I think that the "lint everthing unless we ignore it" approach suits us. We have some files in JSON format that do not belong to the tokens folder and now they are also subject to the linter rules.
