Consider using the "live" stream name for the HASS card automatically, especially if go2rtc is configured

Is your feature request related to a problem? Please describe.

I have a (truncated) frigate config like this:

go2rtc:
  streams:
    CamRecord:
    - rtsp://REDACTED/cam/realmonitor?channel=1&subtype=0
    - ffmpeg:GarageCamEastRecord#audio=copy#audio=opus#video=h264#hardware
    CamDetect:
    - rtsp://REDACTED/cam/realmonitor?channel=1&subtype=1
    # (many other cams like this)

cameras:
  Cam:
    ffmpeg:
      inputs:
      - path: rtsp://127.0.0.1:8554/CamRecord
        input_args: preset-rtsp-restream
        roles:
        - record
      - path: rtsp://127.0.0.1:8554/CamDetect
        input_args: preset-rtsp-restream
        roles:
        - detect
    detect:
      width: 704
      height: 480
    live:
      stream_name: CamRecord

The card picks the wrong stream (CamDetect, which is a low res substream). My understanding is that to get it to pick the right stream I have a few options:

• Explicitly set the stream name in the card config to use the CamRecord stream
• Rename the go2rtc streams so that the "main" stream (Record) has the same name as the cam itself

It's possible I missed a different option.

Describe the solution you'd like

Because my config explicitly lists a live stream, the card should use that by default.
