Add "Open Working Tree Version" submenu to commit changes #2788

In the commit details Changes view, the existing "Open" submenu opens the selected file's historical revision using the chosen editor.

Please add a sibling submenu, "Open Working Tree Version", immediately below "Open", with the same editor options.

It should open the actual file from the working directory, including uncommitted changes, without creating a temporary file.

Keep the existing "Open" submenu unchanged. Disable the new submenu if the file does not exist in the working tree.
