Remove the ASK_UPDATED_DATE_LABEL feature flag and template code (#6690)

* Remove the ASK_UPDATED_DATE_LABEL feature flag and template code

The flag was created in September 2020 to test new wording for the editing
time stamp on Ask CFPB answer pages. The flag was enabled, in 2020, and the new wording,
"LAST REVIEWED," appears to have been in use since.

* rerun translations to fix notes
