fix: accept log levels supported by older zot versions, validate configured log level (#3639)

In zot config accept the same log levels as in https://github.com/rs/zerolog/blob/5391dd7c34c86c2a3b731cd3c3f1b252706e7925/globals.go#L37
This is to maintain backward compatibility with other zot version configurations.
