[examples] Update remark dependency for blog-starter (#33313)

Upgrade remark-html dependency to resolve the critical vulnerability.

Newer versions like 15.0.1 do not work with this example but version 13.0.2 fixes the security issue and still works.
```
                       === npm audit security report ===

# Run  npm install remark-html@15.0.1  to resolve 1 vulnerability
