As a frontend user, I want to easily find other documents on the same fragment in order to better interpret the images and gain context.

testing notes

On the test site, documents that share the same fragment should now be linked to each other  — links should display under the description & secondary metadata, and should only link to public documents (not suppressed).

Note, I put this before transcription+image because I thought if it came after people are more likely to miss it. LMK if you want it moved when you test.

Here are some sample documents & cases to test, but you may want to check others:

• section should not display if no other public documents are on the same fragment
• should not link to suppressed document on the same fragment (test with PGPID 2661 and PGPID 35058)
• single fragment, multiple documents: PGPID 494
• multiple fragments, multiple documents: PGPIDs 31147; 31149; 494, 6178

Is your feature request related to a problem? Please describe.
The admin site now makes it easy to click on related fragments/documents, but the frontend solution is to search the shelfmark and open both/multiple entries separately. It would also be easy to not realize part of the fragment has already been described if you've found the document through a different search term.

Describe the solution you'd like
Below the image/transcription, there should be live links to other PGPID document detail pages for the same/related fragment(s).
