Subject: [PATCH] Implement Refresh on DocumentProvider

"When interacting with DocumentUI or the built-in Android System Internal Files Manager app and performing Create, Rename, and Delete operations, DocumentsUI will not automatically refresh the changes.
Previously, users had to manually pull down from the top to refresh the changes. This commit aims to fix this issue by automatically notifying the system that changes have occurred and triggering a requery."
