Bug 5260: QA follow-up - Add sample ACQORDER notice to sample notices

Adds the new notice ACQORDER to all web installers.

Verify by testing the SQL contains no errors and by running:
perl xt/sample_notices.t

NOTE:
- de-DE is already translated, others are in English.
- xt/sample_notices.t doesn't check fr-CA yet. I didn't fix this here
  as the file is missing other notices as well which should be fixed
  separately.
