Quick affordance long-press failure string updated

The previous string included "to open" but many quick affordances do not
open anything (instead they turn something on or off, like the
flashlight, for example). After discussing with the UX writer, we
decided on this, more generic text.

Bug: 262776614
Test: made sure that the new string renders properly when the quick
affordance is tapped instead of long-pressed
