The update-types configuration only includes "minor" and "patch" updates, which means major version updates for GitHub Actions will be excluded. This could result in missing important updates, security fixes, or new features that come with major version releases. Consider adding "major" to the update-types list, or remove the update-types restriction entirely to allow all types of updates. If the exclusion of major updates is intentional to avoid breaking changes, consider adding a comment explaining this decision.
