Make JSON lint faster

[Syndesi]

The last JSON lint task took more than 5 minutes to parse all 1500+ JSON files.
This could likely be speed up by using more up to date tools like https://github.com/prantlf/jsonlint or some rust based JSON linter.

Acceptance criteria:

• Explore different solutions
• Solutions can be executed locally and in CI/CD environments, i.e. through Docker
• JSON lint rules are similar or identical
