Rulesets have a `source` attribute for the property condition to select if a custom or system property is used. It is documented [here](https://docs.github.com/en/rest/orgs/rules?apiVersion=2022-11-28#create-an-organization-repository-ruleset). It is missing in the [`RulesetRepositoryPropertyTargetParameters`](https://github.com/google/go-github/blob/90bf4320bf6c2703f1c83918e30c5aaf6c93e795/github/repos_rules.go#L52) struct.
