New maintained fork

Hi @epoberezkin, I see the last commit in this repository is three years ago, and it looks like it’s been unmaintained since then. Would you please consider adding a new maintainer?

I’ve forked [ajv-cli](https://github.com/jirutka/ajv-cli/) and made many improvements and changes (see [readme](https://github.com/jirutka/ajv-cli/?tab=readme-ov-file#changes-from-ajv-cli-5)). I’d be happy to contribute it back and maintain it as part of the ajv-validator organisation.
