fix(keybindings): stop the menu ellipsis trailing off inside a sentence

Rebinding a chord that another action holds prints "{action} took the
shortcut from {previous}, which is now unset." Both names come off the
keybindings page, where a command that opens something carries a "…" —
so the note read "Rename Tab… took the shortcut from Close Pane / Tab",
and the marker that means "this opens a dialog" turned into a sentence
losing its nerve.

The ellipsis is a menu convention, not punctuation, so it comes off when
the name is interpolated into prose. The rows themselves keep it.
