Create a citation generation service

[dsenalik]

Task Description

This comment https://github.com/tripal/tripal/pull/1960#issuecomment-2377718708 points out that we currently generate a citation for a publication in at least two different ways. We should have a citation generation service so this can be done in a consistent manner. Bonus: This can also be added to the manual publication entry form, so that we can generate the citation automatically if one was not entered.
