kyverno: reduce length of some fields
Some fields may get too long when templated with the tool name.
Example:
Policy.kyverno.io "toolforge-wikidata-redirects-conflicts-reports-pod-policy" is invalid: [spec.rules[0].name: Too long: may not be longer than 63, spec.rules[1].name: Too long: may not be longer than 63]",
