Update our audit CSVs to use the new Audit template

We should update the generate-bugzilla-triage-csv script so that the "New Issue" hyperlinks use our "Audit" template and use the newer labels.

I.e. replace description= with description_template=120 Bugzilla Audit. This will mean that we would have to copy and paste the bugzilla id by hand from the title to the bugzilla URL in the issue, but I think this would be fine and worth having the CSV link stay up to date with any changes we make to the audit template. It also means that we couldn't automatically /relate it to the versioned audit issue, but I'm not sure this relation is actually that useful.
