Input docs API parameter

[natoverse]

This adds an optional input docs param to the indexing API. Several users have requested the ability to skip input finding/parsing and just supply the dataframe directly, so this provides a mechanism to do so.

Pull Request Overview

This PR adds an optional input_documents parameter to the GraphRAG indexing API that allows users to bypass document loading and parsing by supplying a pre-processed DataFrame directly. This addresses user requests to skip the input finding/parsing step when documents are already available in DataFrame format.

• Adds input_documents parameter to indexing API functions
• Implements logic to write supplied DataFrames directly to storage and skip document loading workflows
• Adds a demonstration notebook showing how to use the new feature
• Removes unused workflow registration function
