Describe the bug

I'm not sure whats intended, but for me the doc doesn't match the actual configuration schema.

Here it says site.meters.consumer
https://docs.evcc.io/en/user-defined-devices/#meter

But in the evcc.yaml I need to set site.meters.consumers otherwise evcc will complain it can not have consumer within meters

Note: I haven't checked the nightly but the code on main:

Steps to reproduce

1.Have a meter configured in evcc.yaml
2. Reference it in site with missing plural s

site:
  title: Mein Zuhause
  meters:
    consumer: 
      - Waermepumpe

3. Start evcc, see log for error

Configuration details

site:
  title: Mein Zuhause
  meters:
    grid: grid
    pv:
      - Fronius
    consumers: 
      - Waermepumpe
