Author parsing when authors are parameterized as templates

[ndrezn]

Occassionally authors for photographs are annotated using templates, see: https://commons.wikimedia.org/wiki/File:Red-and-green_macaw_(Ara_chloropterus)_juvenile.JPG on https://en.wikipedia.org/wiki/Template:POTD/2022-09-07 and https://en.wikipedia.org/wiki/Template:POTD/2022-09-06. These templates should be parsed and converted to strings as part of the attribution reply. For now attribution in these cases only includes the link to the photograph.
