Correct a typo in the 1.4 changelog

Change-Id: Ib7d1fc75957ad2efb348fee9d862d75b06dbafef

Fixed issue in future :class:`_future.Engine` where calling upon
:meth:`_future.Engine.begin` and entering the context manager would not
close the connection if the actual BEGIN operation failed for some reason,
such as an event handler raising an exception; this use case failed to be
tested for the future version of the engine. Note that the "future" context
managers which handle ``begin()`` blocks in Core and ORM don't actually run
the "BEGIN" operation until the context managers are actually entered. This
is different from the legacy version which runs the "BEGIN" operation up
front.

Fixes: #7272

Removed the previously deprecated ``case_sensitive`` parameter from
:func:`_sa.create_engine`, which would impact only the lookup of string
column names in Core-only result set rows; it had no effect on the behavior
of the ORM. The effective behavior of what ``case_sensitive`` refers
towards remains at its default value of ``True``, meaning that string names
looked up in ``row._mapping`` will match case-sensitively, just like any
other Python mapping.

based on feedback in #7271, the emphasis on TypeDecorator
as a solution to this problem is not very practical.  illustrate
a series of quick recipes that are useful for debugging purposes
to print out a repr() or simple stringify of a parameter
without the need to construct custom dialects or types.

in order to remove LegacyRow / LegacyResult, we have
to also lose close_with_result, which connectionless
execution relies upon.

also includes a new profiles.txt file that's all against
py310, as that's what CI is on now.  some result counts
changed by one function call which was enough to fail the
low-count result tests.

Replaces Connectable as the common interface between
Connection and Engine with EngineEventsTarget.  Engine
is no longer Connectable.  Connection and MockConnection
still are.
