Update strings again for refreshed High Contrast Text

Deletes the old string resource and uses a new resource because the old
translated strings do not have formatting placeholders. Eventually the
old translated strings will be automatically deleted and the new string
with placeholder will be translated.

Also uses placeholders for referencing other strings so that
we guarantee that the strings are consistent across this notification
and the actual preference in Settings.
