feat: add automated commenting on linked issues when releases are published

[KyleAMathews]

Summary

Enhances the comment-on-release action to automatically notify both PRs and their linked issues when changes are released, matching the functionality from electric-sql/electric#3521.

Changes

• Query linked issues: Uses GitHub's GraphQL API to find issues that each PR closes/fixes
• Comment on issues: Posts release notifications on linked issues with package version info
• Duplicate detection: Checks for existing comments to prevent spam if workflow runs multiple times
• Enhanced permissions: Adds explicit issues: write permission to release workflow
• Updated documentation: README reflects new issue commenting functionality

Example Comments

On a PR:

🎉 This PR has been released!

- [@tanstack/config@1.2.0](...)

Thank you for your contribution!

On a linked issue:

🎉 The PR fixing this issue (#123) has been released!

- [@tanstack/config@1.2.0](...)

Thank you for reporting!

How It Works

After commenting on PRs, the action:

1. Queries GitHub's GraphQL API for issues closed by each PR
2. Groups issues and tracks which PRs fixed them
3. Posts a single consolidated comment per issue
4. Checks for existing comments before posting to avoid duplicates

Test Plan

• Verify GraphQL query correctly finds linked issues
• Test duplicate comment detection
• Confirm proper permissions in workflow
• Validate comment formatting on both PRs and issues
• Test with multiple packages affecting same PR/issue
