Delete "examples/data/hotel_invoices/extracted_invoice_json " directory

[CWu101]

Summary

This PR removes a folder whose name ends with a space (extracted_invoice_json ), which causes an error during git clone:

error: invalid path 'examples/data/hotel_invoices/extracted_invoice_json /20190119_002_extracted.json '
fatal: unable to checkout working tree

This fixes the checkout failure and ensures the repository can be cloned successfully.

Motivation

A folder name ending with a space is not supported by many filesystems (e.g., NTFS on Windows), leading to fatal errors when cloning the repository. Removing or renaming the folder resolves this issue and improves cross-platform compatibility. This change also addresses issue #1837.

The deletion only affects the malformed folder with a trailing space. A valid data folder examples/data/hotel_invoices/extracted_invoice_json remains intact(containing the exact same content as the deleted folder), ensuring that the only script relying on it examples/Data_extraction_transformation.ipynb continues to function correctly.
