Data Tables View breaks for 'en_AU' locale

[ThrawnCA]

CKAN version

2.10

Describe the bug

When using the 'en_AU' locale, Data Tables views frequently fail to load.

Steps to reproduce

• Create a resource and generate a Data Tables view.
• Load the resource page from a location in Australia.

Expected behavior

Additional details

This appears to be because there is no 'en_AU.json' entry in ckanext/datatablesview/public/vendor/DataTables/i18n/.

The contents would be the same as en_GB.json.

Firefox console:
