python3-sqlalchemy: upgrade 1.4.20 -> 1.4.22

.. changelog::
    :version: 1.4.22
    :released: July 21, 2021

    .. change::
        :tags: bug, sql
        :tickets: 6786

        Fixed issue where use of the :paramref:`_sql.case.whens` parameter passing
        a dictionary positionally and not as a keyword argument would emit a 2.0
        deprecation warning, referring to the deprecation of passing a list
        positionally. The dictionary format of "whens", passed positionally, is
        still supported and was accidentally marked as deprecated.

    .. change::
        :tags: bug, orm
        :tickets: 6775

        Fixed issue in new :meth:`_schema.Table.table_valued` method where the
        resulting :class:`_sql.TableValuedColumn` construct would not respond
        correctly to alias adaptation as is used throughout the ORM, such as for
        eager loading, polymorphic loading, etc.

    .. change::
        :tags: bug, orm
        :tickets: 6769

        Fixed issue where usage of the :meth:`_result.Result.unique` method with an
        ORM result that included column expressions with unhashable types, such as
        ``JSON`` or ``ARRAY`` using non-tuples would silently fall back to using
        the ``id()`` function, rather than raising an error. This now raises an
        error when the :meth:`_result.Result.unique` method is used in a 2.0 style
        ORM query. Additionally, hashability is assumed to be True for result
        values of unknown type, such as often happens when using SQL functions of
        unknown return type; if values are truly not hashable then the ``hash()``
        itself will raise.

        For legacy ORM queries, since the legacy :class:`_orm.Query` object
        uniquifies in all cases, the old rules remain in place, which is to use
        ``id()`` for result values of unknown type as this legacy uniquing is
        mostly for the purpose of uniquing ORM entities and not column values.

 .. change::
        :tags: orm, bug
        :tickets: 6771

        Fixed an issue where clearing of mappers during things like test suite
        teardowns could cause a "dictionary changed size" warning during garbage
        collection, due to iteration of a weak-referencing dictionary. A ``list()``
        has been applied to prevent concurrent GC from affecting this operation.

    .. change::
        :tags: bug, sql
        :tickets: 6770

        Fixed issue where type-specific bound parameter handlers would not be
        called upon in the case of using the :meth:`_sql.Insert.values` method with
        the Python ``None`` value; in particular, this would be noticed when using
        the :class:`_types.JSON` datatype as well as related PostgreSQL specific
        types such as :class:`_postgresql.JSONB` which would fail to encode the
        Python ``None`` value into JSON null, however the issue was generalized to
        any bound parameter handler in conjunction with this specific method of
        :class:`_sql.Insert`.

    .. change::
        :tags: bug, engine
        :tickets: 6740

        Added some guards against ``KeyError`` in the event system to accommodate
        the case that the interpreter is shutting down at the same time
        :meth:`_engine.Engine.dispose` is being called, which would cause stack
        trace warnings.

    .. change::
        :tags: bug, orm, regression
        :tickets: 6793

        Fixed critical caching issue where the ORM's persistence feature using
        INSERT..RETURNING would cache an incorrect query when mixing the "bulk
        save" and standard "flush" forms of INSERT.
