Merge branch 'release-v31.1' into develop
Fix 7598: Preserve closed square brackets in displayDate but
remove single, unclosed brackets
Refactored views to eliminate separate *_count views (#7545)

https://issues.dp.la/issues/7545

Upgrading:  This is being released alongside an update to the
platform (API) application, which changes the QA interface's
generation of reports.  The sync_couch_views.py script should
be run against the 'dpla' database, ideally before the views are
actually needed.
Fix 7612 - Update date and temporal mapping

- Remove enrich_date from pipeline so that temporal is left alone
- Date year range function should only ensure that list values are
  in increasing order, rather than sequential
Bumped version to 31.2
