9075d1f662 [3.1.x] Fixed #31936 -- Fixed __in lookup on key transforms for JSONField.
This resolves an issue on databases without a native JSONField
(MariaDB, MySQL, SQLite, Oracle), where values must be wrapped.

Thanks Sébastien Pattyn for the report.

247bcef6b4 [3.1.x] Fixed #31836 -- Dropped support for JSONField __contains and __contained_by lookups on SQLite.
The current implementation works only for basic examples without
supporting nested structures and doesn't follow "the general principle
that the contained object must match the containing object as to
structure and data contents, possibly after discarding some
non-matching array elements or object key/value pairs from the
containing object".
