Remove Blog link from README.md

[Copilot]

📋 Summary

This PR removes the Blog link from README.md as the team has decided to keep old blog posts for backlinks but not actively promote them anymore.

🎯 What

Removed the Blog link and its associated separator from the navigation section of README.md.

🤔 Why

The /blog link was pointing to a non-existent page (404 error). After discussion, the decision was made to remove the link rather than create a blog index page, since the blog is no longer being actively promoted.

🔧 How

• Removed the <a href="https://polar.sh/blog">Blog</a> link from line 20 of README.md
• Removed the associated navigation separator to maintain proper formatting

🧪 Testing

• I have tested these changes locally
• All existing tests pass (uv run task test for backend, pnpm test for frontend)
• I have added new tests for new functionality
• I have run linting and type checking (uv run task lint && uv run task lint_types for backend)

Test Instructions

1. View the README.md file
2. Verify the Blog link is no longer present in the navigation section
3. Verify the remaining links (Website, Docs, API Reference) are properly formatted

📝 Additional Notes

This is a minor documentation fix that resolves a broken link by removing it rather than creating additional infrastructure.

This section details on the original issue you should resolve

<issue_title>Broken Blog link in README.md, add blog index page?</issue_title>
<issue_description>### Description

The Blog link in README.md currently points to /blog, which returns a 404 because only individual post pages exist.

This initially looked like a minor fix (broken link), but I ended up adding a simple /blog index page that lists existing posts and follows the existing site styling, so users landing on /blog can discover the available content instead of encountering a 404 error.

8730 has a possible solution for reference. Happy to adjust the approach, rework it, or close it entirely if you'd prefer a different solution :)

Current Behavior

Navigating to /blog results in a 404 page.

Expected Behavior

Navigating to /blog points to a valid destination.

@frankie567 Thank you, that's a fair point :D But I think we'll just remove the Blog link from the README, I think we just keep the old posts for backlinks but not promote them anymore.
