Here's a grab bag of trivial cleanup to the documentation. This change:
- Cleans up some comments in the asciidoctor macros which are no longer
accurate (and do not appear in the build products anyway).
- Fixes a missing space in the text "Wireshark Q&A" in the release notes.
- Allows the "docbook" backend to produce hyperlinks too... That seems to be
necessary if we want to start using our custom link macros in WSDG, which
seems like a reasonable thing to do. And fixes up a wrong variable name in
the handling of the case where we are not able to produce a hyperlink.
