[DOC] Update custom EF code sample

[kylediaz]

This updates the sample code to show how to use custom EFs correctly. The old snippets would result in legacy EFs.

You need to register the EF, and if you don't define the extra functions it's considered a legacy EF.

Reviewer Checklist

Please leverage this checklist to ensure your code review is thorough before approving

Testing, Bugs, Errors, Logs, Documentation

• Can you think of any use case in which the code does not behave as intended? Have they been tested?
• Can you think of any inputs or external events that could break the code? Is user input validated and safe? Have they been tested?
• If appropriate, are there adequate property based tests?
• If appropriate, are there adequate unit tests?
• Should any logging, debugging, tracing information be added or removed?
• Are error messages user-friendly?
• Have all documentation changes needed been made?
• Have all non-obvious changes been commented?

System Compatibility

• Are there any potential impacts on other parts of the system or backward compatibility?
• Does this change intersect with any items on our roadmap, and if so, is there a plan for fitting them together?

Quality

• Is this code of a unexpectedly high quality (Readability, Modularity, Intuitiveness)

Update custom embedding function documentation examples

Refreshes the custom embedding function examples to reflect current registration and persistence requirements. Adds richer Python and TypeScript snippets that demonstrate naming, configuration serialization, and rebuild hooks alongside the register_embedding_function decorator.

Key Changes

• Expanded the Python example MyEmbeddingFunction to include register_embedding_function, constructor storage of model, name, get_config, and build_from_config helpers using Dict[str, Any]
• Replaced the TypeScript example with a class that exposes name, getConfig, validateConfigUpdate, and buildFromConfig, while returning placeholder embeddings and preserving configuration
• Maintained the provider/package table formatting adjustments to normalize spacing in the TypeScript embedding packages list
