chore: exclude chart folder from license check. (#3397)

We chose to skip the check in chart repository because although it is a yaml file, the comment structure for the helm templates requires a different format than yaml (see https://github.com/openzipkin/zipkin/pull/3378\#issuecomment-933235104) and even with custom header type we can't match both.
