agent: Fix edit_file tool description (#48588)

Vianney le Clément de Saint-Marcq created 

This patch updates the description of the `edit_file` tool to recommend
models to use the `move_path` tool instead of the `terminal` tool to
move or rename files. The `move_path` tool is more specific and shall be
preferred as it provides a better UI and dedicated permissions.

Release Notes:

- N/A
