fix: for code scanning alert no. 2: Workflow does not contain permissions

[VisualBean]

Potential fix for https://github.com/ByteBardOrg/AsyncAPI.NET/security/code-scanning/2

Add an explicit top-level permissions block in .github/workflows/do_not_merge.yml so the GITHUB_TOKEN is restricted to least privilege for all jobs in this workflow.
Best single fix without changing behavior: set permissions: { contents: read } at workflow root (between on: and jobs:). This preserves functionality for a label-check workflow while avoiding inherited broad write scopes. No imports, methods, or additional definitions are needed.

Suggested fixes powered by Copilot Autofix. Review carefully before merging.

Warning

Review limit reached

@VisualBean, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 59 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
