add back links to issues from nb comments

[JeffGarland]

This PR covers links to all the current issues linked from nbballots. I took as slightly different style than a few of the recent issues that just put bold text into the description -- here I made it a note and put the link to the repo. I didn't modify some of the ones that already had these 'text references'.

other notes: I notice the mdash, hellip, and sect give errors from xmllint. These might need to be added to the dtd?

They're all in the DTD already, are you telling xmllint to use the DTD?

The relevant option is --dtdvalid xml/lwg-issue.dtd

Or just use bin/lint.sh in the repo which checks everything.

The "Validate XML" CI workflow use bin/lint.sh too, so pull requests are checked.

No - naively I was thinking xmllint would pick them up from header if running in the xml directory.

<!DOCTYPE issue SYSTEM "lwg-issue.dtd">

roger that. ironically I just pulled out xmllint bc it's what installed on the mac without even thinking of looking in bin.
