Notebook on web crawling

[WilliamEspegren]

Why are these changes needed?

Lacking web crawling examples in both notebooks and the docs/Example.md

Checks

Not any applicable right?

• I've included any doc changes needed for https://microsoft.github.io/autogen/. See https://microsoft.github.io/autogen/docs/Contribute#documentation to build and test documentation locally.
• I've added tests (if relevant) corresponding to the changes introduced in this PR.
• I've made sure all auto checks have passed.

I referred to a previous pull request for inspiration while creating this notebook example for Spider. This PR provided a helpful reference for structure and content, which I have adapted to fit the specific requirements of Spider.

Thanks. Would you like the notebook to be rendered on the website? If so, https://github.com/microsoft/autogen/blob/main/notebook/contributing.md#how-to-get-a-notebook-displayed-on-the-website is the guide.

Some metadata needs to be added for it to render. It's OK to do it in a separate PR if you like.

🛠 Guidelines to remediate hardcoded secrets

1. Understand the implications of revoking this secret by investigating where it is used in your code.
2. Replace and store your secrets safely. Learn here the best practices.
3. Revoke and rotate these secrets.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.
