Finalize text of per-profile IME settings

This is a follow up CL to a recent CL [1], which updated text in the
Settings app as follows:
 * "Keyboard & inputs" to "Keyboards"
 * "Input assistance" to "Tools"

For consystency, this CL updates the header text for the work-profile
specific enties in Languages & input from
  Work profile input & assistance
to
  Work profile keyboards & tools.

Other than that, there is no user-visible behavior change.
