In case of a duplicate YAML key, our configuration check will just pass. However, when actually using the configuration, Home Assistant will throw errors in the log. This is handled gracefully. Home Assistant will continue to work.

Hence, an ERROR level log message might suggest differently. (See raised issue #22525). This PR downgrades the log level to WARNING in case of a duplicate key.
