Configlet `lint` does not touch Approaches config.json

Somewhat surprisingly to me, community contributions to exercism/configlet are paused, so I’m reporting this here.

It seems configlet fmt does not look for config.jsons in .approaches directories. I feel it should.

In the meantime: is there a preferred formatting tool? A (very) quick look through configlet’s code did not turn up any.

Yes, this is something we haven’t yet implemented. @ee7-1282 thoughts on how hard it would be to add that?

We don’t have a preferred formatting tool. We’re using a Nim library to handle formatting internally.
