feat: Add file name to knowledge properties in crawl_endpoint (#3346)

The `crawl_endpoint` function in `crawl_routes.py` now includes the
`file_name` property in the `knowledge_to_add` object. This change
ensures that the file name is properly associated with the crawled
knowledge, improving the accuracy and organization of the data.
