Fix Broken Documentation Links (#1275)

* Update URL for PDFMARK documentation

For reference, here is a link to the old PDF:
https://web.archive.org/web/20190806035303/https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/pdfmark_reference.pdf

It appears Adobe converted the PDF into a webpage-based document, the
wording seems to almost identical b/w the PDF and the website.

* Fix cross-references to JBIG2 page

* Fix links for Fedora + Arch + HEAD revision install

Fedora 39 has been released, and the package tracker no longer includes
a release overview for Fedora 37 hence why it was removed here.
