Swap JSONField to django.db.models.JSONField

[jslay-excella]

The currently used JSONField (django.contrib.postgres.fields.JSONField) is deprecated. Django now has django.db.models.JSONField supporting postgres.

crtool.CurriculumReviewSession.data: (fields.W904) django.contrib.postgres.fields.JSONField is deprecated. Support for it (except in historical migrations) will be removed in Django 4.0.
        HINT: Use django.db.models.JSONField instead.

Changes

• crtool.CurriculumReviewSession.data changed to django.db.models.JSONField
