Validating JQ schematics in VScode

[JaneX8]

Moving this issue into a discussion @wader.

Validating JQ structures like this:

{
  "name": "Example",
  "data": [
    # __JQ_START__
    .input | map({ key: .key, value: .value })
    # __JQ_END__
  ]
}

Either with or without placeholders like __JQ_START__.
