Add service definition for Frigate

Description: Frigate is an NVR service that uses AI accelerators like the Coral TPU or GPUs to perform low latency object detection on IP Camera streams

Official Website: https://github.com/blakeblackshear/frigate

Default Ports: tcp/5000 but is often deployed behind a reverse proxy, so standard https on tcp/443

Discovery Method: Trying to match <title>Frigate</title> in either the container or proxy response.

• Pattern type: Endpoint
• Reasoning: This one is kind of tricky - there are no other open health or metrics endpoints, and the only identifying string in the unauthenticated response is this title tag.
