Update Cookbook notebooks with fixes and improvements

[shreekant-openai]

Summary

Updates existing Cookbook notebooks to make the Evals, Qdrant, and knowledge retrieval examples more current, executable, and easier to follow.

This PR includes:

• Modernized model references where examples used older model names.
• Updated Qdrant examples to use current client APIs.
• Clearer setup and execution guidance for the OpenAI Evals notebook.
• Small fixes for notebook execution reliability.
• Cleanup of stale saved-output noise where applicable.
• An update to the Qdrant Docker setup used by the vector database examples.

This PR does not add new Cookbook content; it refreshes existing notebooks so they remain useful and accurate for readers.

Motivation

Some existing notebooks had become stale as API patterns, model names, and third-party client usage evolved. A few examples also had setup or execution gaps that could make them harder for readers to run successfully.

These updates improve the Cookbook by making the affected examples:

• More aligned with current OpenAI API usage.
• Easier to execute from a clean environment.
• Clearer in their setup instructions.
• Less likely to run into deprecated dependency or client-method behavior.
• Better aligned with current notebook quality expectations.

Validation performed:

• Ran git diff --check.
• Ran full real notebook validation with nbclient for the changed notebooks:
  • examples/How_to_call_functions_for_knowledge_retrieval.ipynb
  • examples/evaluation/Getting_Started_with_OpenAI_Evals.ipynb
  • examples/vector_databases/qdrant/Getting_started_with_Qdrant_and_OpenAI.ipynb
  • examples/vector_databases/qdrant/Using_Qdrant_for_embeddings_search.ipynb

Qdrant validation included starting a local Qdrant Docker service, running the notebooks, then stopping and removing the temporary container/network. Generated runtime datasets and zip files were removed and are not included in this PR.

For new content

This PR updates existing content only and does not add a new Cookbook entry.

• I have added a new entry in registry.yaml (and, optionally, in authors.yaml) so that my content renders on the cookbook website.
• I have conducted a self-review of my content based on the contribution guidelines:
  • Relevance: This content is related to building with OpenAI technologies and is useful to others.
  • Uniqueness: I have searched for related examples in the OpenAI Cookbook, and verified that my content offers new insights or unique information compared to existing documentation.
  • Spelling and Grammar: I have checked for spelling or grammatical mistakes.
  • Clarity: I have done a final read-through and verified that my submission is well-organized and easy to understand.
  • Correctness: The information I include is correct and all of my code executes successfully.
  • Completeness: I have explained everything fully, including all necessary references and citations.
