Release comment gate should not count approval-only reviews

[gaelic-ghost]

Summary

The maintain-project-repo release helper's check_pr_comments gate counts every GitHub review object as a blocking comment, even when the review is approval-only and has no actionable comment thread.

Observed behavior

In a downstream gaelic-ghost/SpeakSwiftlyServer release PR, the generated scripts/repo-maintenance/release.sh comment gate used a query shaped like this:

gh pr view "$pr_number" --json comments,reviews --jq '([.comments[]?, .reviews[]?] | length)'

Because .reviews includes approvals and other review states, an approval-only review can make the release script think there are unresolved comments. In standard release mode, that forces maintainers to pass the review-comments override even when there is no actionable feedback left to address.

Expected behavior

check_pr_comments should only count actionable review objects or comment-bearing review states.

The downstream fix in SpeakSwiftlyServer was to count only COMMENTED reviews:

gh pr view "$pr_number" --json comments,reviews --jq '([.comments[]?, .reviews[]? | select(.state == "COMMENTED")] | length)'

That keeps approval-only reviews from blocking release preparation while preserving the guard for actual PR comments and comment-style reviews.
