Add 1337 Services GmbH to Good/Bad ISPs page/JSON file

I got a JSON blob thrown over the wall today with the ask of adding it to our Good/Bad ISP material:

      { "name": "1337 Services GmbH",
        "url": "https://rdp.sh",
        "asn": "AS210558",
        "bridge": "Yes",
        "relay": "Yes",
        "exit": "Yes",
        "comment": "",
        "last_updated": "04/2025"
      },

Sounds worthwhile IMO, @gus.
