v1.7 - Wagtail 5.2 support

This is the full release with Wagtail 5.2/Python 3.12 support, provisional Wagtail 6 support, and a fix for DeepL target language code.

Note

If you are using wagtail_localize.modeladmin it is recommended to use wagtail-modelamind as the wagtail.contrib.modeladmin was deprecated in Wagtail 5.0 and will be removed in Wagtail 6.0

• Prep for 1.7, add provisional Wagtail 6 support by @zerolab in #742
