Bad link in template.nasl

In the template.nasl referenced by VT Development, the line for script_family() includes the comment:

# Use only one of the predefined ones, see http://www.openvas.org/openvas-cr-23.html

That resource apparently no longer exists. What names are in the set of predefined script families?

Also, FWIW, https://docs.greenbone.net/GSM-Manual/gos-4/en/glossary.html#quality-of-detection-qod (referenced in the VT Development doc) also no longer exists.
