missing documentation

[dlschwartz]

@wsalesky It looks like we are missing some info on the following pages

• https://syriaca.org/documentation/view-teiDocs.html
• https://syriaca.org/documentation/confessions.html (used to contain this list: https://github.com/srophe/srophe-eXist-app/blob/master/documentation/confessions.xml)
