Local function which adds the names relevant TV series to the args table.
Franchise templates, such as the Arrowverse-specific one, have short parameters that editors can use
instead of the full TV series name.
This functions checks if the user-input parameters match the ones on the list,
and if they do, adds them to the list.

Franchise templates can also use a "franchise" default parameter
so all members will automatically be tagged in the franchise category,
as well as the specific TV series category.
