Display ingested file paths instead of file names

[omartrigui]

Description

The current implementation only displays the ingested filenames, which can be confusing for users when the specified directory for ingestion contains nested directories with multiple levels. Additionally, the existing implementation discards files with different names e.g. a root_path directory contains index.md, dir1/index.md, dir2/index.md, only one single index.md file is displayed. This PR enhances the display by including the file paths instead of just filenames, addressing the potential confusion caused by nested directories, and ensures that all files are appropriately displayed without discarding any.

Personally this would break my use case for PGPT for me. Almost all of my items are web URLS. So the "filename" is actually the URL of a confluence page, web article, policy, etc...

This PR would not work with how I use PGPT. Not sure how others feel, but I think this should be a toggleable (Off by default) setting.

IMO.

+1 for an option
While my use case will benefit from this PR, the current behaviour should remain default to avoid breaking setups or resulting in unexpected results, but an option to switch to path display and allowing files with the same filename in different folders would be great!
Thanks.
