Drop the GUI capture shortcut from the manual (developer-only)

Ctrl+Alt+Shift+C is a developer affordance and does not belong in the user
manual (author's decision). Removed from the application-wide table in all 11
languages. The Option menu entry "(experimental) Capture GUI Components" stays
documented in 0-main-window, since that row describes a menu item that is
visible in the GUI.

This also retires the row's claim that the menu item had to be enabled first,
which was wrong - the message filter is installed unconditionally.

mkdocs --strict builds clean.
