Create nodejs vector database examples set

[tylerhutcherson]

Create Node vector database examples for each of the following features using the Python OpenAI cookbook as a reference:

• JSON + VSS
• Hybrid Querying
• QnA
• performance "fine tuning"

Contribute the code examples either in jupyter notebook or as a script with comments. We will want this to be testable by a CI agent moving forward. Feel free to leverage assets you've already made in order to accelerate the development,. but we need to aggregate these here for optimal reach.
