Support batching inline comments into a single GitHub Pull Request Review submission #1049
Description
Currently the action posts each inline comment as an independent API call, resulting in multiple separate comment notifications on a PR. GitHub provides a dedicated Pull Request Reviews API designed specifically for this use case — it lets a reviewer stage multiple inline comments and submit them together as a single review event with an overall status (COMMENT, APPROVE, or REQUEST_CHANGES).
Requested behavior:
Add an input (e.g. use_pr_review) that, when enabled, collects all inline comments and submits them together via POST /repos/{owner}/{repo}/pulls/{pull_number}/reviews rather than posting each as an individual comment.
Why this matters:
- Reduces notification noise — PR authors currently get one notification per comment rather than one for the entire review
- Produces a cohesive review that appears in GitHub's "Reviews" section of the PR timeline, matching the experience of a human reviewer
- Allows an overall review verdict to accompany the inline feedback
- Avoids cluttering the PR comment thread with many independent entries

use_sticky_comment addresses a similar concern for top-level comments but doesn't apply to inline code comments, and doesn't use the GitHub review submission model.
