Description

What would you like to be added

Add a manual test sample that lets the user do the following:

  1. Pick a file using FileOpenPicker
  2. Modifies the file (e.g. using FileIO)
  3. The user then checks if the file has been modified at the source location (e.g. using file explorer)

Research direction
Start by reviewing existing manual test samples in the repository (e.g., under the manual tests directory). The issue requires using `FileOpenPicker` and `FileIO` APIs. Implement a simple UI to pick a file, modify its content, then verify the changes externally. Check the Uno documentation for cross platform file API usage. No linked PRs or assignees, so the work is available.
