Correct the RestoreOption_SkipMainWindowVisibility documentation.

The following documentation line says that layout restoration will not change main-window geometry. It now follows the visibility-only option, while framework/dockwindow/thirdparty/KDDockWidgets/src/LayoutSaver.cpp Line 255 still restores geometry when only this flag is set. Move that sentence back to RestoreOption_RelativeToMainWindow, or replace it with visibility-only wording.

Proposed documentation fix 
 RestoreOption_RelativeToMainWindow = 1, ///< Skips restoring the main window geometry and the restored dock widgets will use relative sizing.
+    ///< Loading layouts won't change the main window geometry and just use whatever the user has at the moment.
 RestoreOption_SkipMainWindowVisibility = 2, ///< Don't show/hide the main window according to the saved layout when restoring.
-    ///< Loading layouts won't change the main window geometry and just use whatever the user has at the moment.

In `@framework/dockwindow/thirdparty/KDDockWidgets/src/KDDockWidgets.h` at line
186, Correct the documentation for RestoreOption_SkipMainWindowVisibility so it
describes only skipping saved main-window visibility changes; move the
main-window geometry restoration wording back to
RestoreOption_RelativeToMainWindow if present. Keep the enum behavior unchanged.

///< Loading layouts won't change the main window geometry and just use whatever the user has at the moment.
