Django 4.2.2 fixes several bugs in 4.2.1.

## Bugfixes

- Fixed a regression in Django 4.2 that caused an unnecessary `DBMS_LOB.SUBSTR()` wrapping in the `__isnull` and `__exact=None` lookups for `TextField()`/`BinaryField()` on Oracle (#34544).

- Restored, following a regression in Django 4.2, `get_prep_value()` call in `JSONField` subclasses (#34539).

- Fixed a regression in Django 4.2 that caused a crash of `QuerySet.defer()` when passing a `ManyToManyField` or `GenericForeignKey` reference. While doing so is a no-op, it was allowed in older version (#34570).

- Fixed a regression in Django 4.2 that caused a crash of `QuerySet.only()` when passing a reverse `OneToOneField` reference (#34612).

- Fixed a bug in Django 4.2 where `makemigrations --update` didn’t respect the `--name` option (#34568).

- Fixed a performance regression in Django 4.2 when compiling queries without ordering (#34580).

- Fixed a regression in Django 4.2 where nonexistent stylesheet was linked on a “Congratulations!” page (#34588).

- Fixed a regression in Django 4.2 that caused a crash of `QuerySet.aggregate()` with expressions referencing other aggregates (#34551).

- Fixed a regression in Django 4.2 that caused a crash of `QuerySet.aggregate()` with aggregates referencing subqueries (#34551).

- Fixed a regression in Django 4.2 that caused a crash of querysets on SQLite when filtering on `DecimalField` against values outside of the defined range (#34590).

- Fixed a regression in Django 4.2 that caused a serialization crash on a `ManyToManyField` without a natural key when its `Manager`’s base `QuerySet` used `select_related()` (#34620).
