Make vocab-ssn a series alias of vocab-ssn-2017 (#882)

Previous shortname `vocab-ssn` was renamed to `vocab-ssn-2017` following the
publication of a new version named `vocab-ssn-2023`. The `vocab-ssn` shortname
is now a series alias that currently redirects to `vocab-ssn-2017`.

This update adjusts entries in Specref accordingly (same "usual" problem as
in #877, re-creating dated versions of `vocab-ssn` as needed.
