Django 2.2.7 fixes several bugs in 2.2.6.
Fixed a crash when using a contains, contained_by, has_key,
has_keys, or has_any_keys lookup on
django.contrib.postgres.fields.JSONField, if the right or left hand
side of an expression is a key transform (#30826).
Prevented migrate --plan from showing that RunPython operations
are irreversible when reverse_code callables don’t have docstrings or
when showing a forward migration plan (#30870).
Fixed migrations crash on PostgreSQL when adding an
Index with fields ordering and
opclasses (#30903).
Restored the ability to override
get_FOO_display() (#30931).
