Fix text_field_tag's placeholder documentation [ci skip]

When placeholder set to true on `text_field_tag`, it will try to look up its value from the translation files.
The documentation referenced an incorrect translation key scope, it is defined in [Placeholderable][1] as `helpers.placeholder` (singular).
Followup for #37054

Also improves wording.
