chore(learn): modernize question-answering.ipynb to SDK v8

[jhamon]

Summary

• Update pinecone-client==3.1.0 to pinecone==8.0.0
• Pin all dependency versions (pandas, numpy, matplotlib, ipywidgets, requests, sentence-transformers)
• Fix typos: "quetions" → "questions", "a efficient" → "an efficient"
• Remove marketing phrase "as a service"
• Improve clarity and readability

Test plan

• Verify notebook runs end-to-end without errors
• Check that all imports work with pinned versions
• Validate SDK v8 patterns are followed
• Review writing style matches .ai/writing-guidelines.md

Note

Low Risk
Single-notebook change focused on dependency/version updates and minor text/formatting edits; the main risk is the example not running end-to-end due to SDK/API behavior differences with the newly pinned versions.

Overview
Modernizes the learn/search/question-answering/question-answering.ipynb tutorial to the Pinecone Python SDK v8, including updated install commands and imports while keeping the overall QA similarity-search flow the same.

Pins versions for key notebook dependencies (Pinecone, pandas/numpy/matplotlib/ipywidgets/requests, and sentence-transformers) and includes small documentation polish (typos/wording) plus minor notebook JSON/cell formatting churn from re-serialization.

Positional arguments used instead of named keyword arguments

Low Severity

The create_index call uses index_name as a positional argument rather than a named keyword argument like name=index_name. Similarly, pc.Index(index_name) on line 264 uses a positional argument. The review rules explicitly state to "prefer to use named keyword arguments over positional arguments" for example code clarity. Using name=index_name would make the code more readable and self-documenting for users learning from this notebook.
