fix(keybindings): name the switcher after the command, not the home tile

The keybindings page read ToggleSwitcher's name off the home screen's
string while TogglePalette read its own off the menu bar, so the one
action that appears in both places was the one whose name could drift.
Point it at CmdSwitchWorkspace, the name the palette shows, and pin it
with the assertion the page's other names already carry.
