[Vizio] Replace logger configuration with simple flag (#5672)

The Vizio component has an (to date) undocumented configuration flag which can be used to suppress the self-signed certificate warnings. IMO, this approach is preferable to the currently documented method of using the `logger` component, using a reverse proxy, or setting python environment variables.

-`InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised.`

-You can adjust the log level for `media_player` components with the [logger](/components/logger/) component, or if you need to keep a low log level for `media_player` you could proxy calls to your TV through an NGINX reverse proxy.

-If you want to only ignore only this specific [python urllib3 SSL warning](https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings), you will need to run Home Assistant with the python flag `-W` or the environment variable `PYTHONWARNINGS` set to:
-`ignore:Unverified HTTPS request is being made`
