Add imprimatur and argumentum as allowed values of front and back matter

I propose to add imprimatur (Q955005) and argumentum (Q101247267) as allowed values of front and back matter. Both types of paratexts are present in front matter of an edition of a play from 1709 that I am describing (Q115774326). Tranquillus (talk) 16:07, 2 January 2023 (UTC)
