refactor: Use jq instead of custom posix complient json.sh

While json.sh worked decently for reading json files, I didn't want to
implement writing to json files as well and make it completely
unreadable due to the added complexity.

So, I think its better to just use jq and keep things relatively simple
with the tradeoff of a lightweight dependency
