py-anyio: updated to 4.7.0

4.7.0

- Updated ``TaskGroup`` to work with asyncio's eager task factories
- Added the ``wait_readable()`` and ``wait_writable()`` functions which will accept
  an object with a ``.fileno()`` method or an integer handle, and deprecated
  their now obsolete versions (``wait_socket_readable()`` and
  ``wait_socket_writable()``)
- Changed ``EventAdapter`` (an ``Event`` with no bound async backend) to allow \ 
``set()``
  to work even before an async backend is bound to it
- Added support for ``wait_readable()`` and ``wait_writable()`` on \ 
``ProactorEventLoop``
  (used on asyncio + Windows by default)
- Fixed a misleading ``ValueError`` in the context of DNS failures
- Fixed the return type annotations of ``readinto()`` and ``readinto1()`` \ 
methods in the
  ``anyio.AsyncFile`` class
- Fixed ``TaskInfo.has_pending_cancellation()`` on asyncio returning false \ 
positives in
  cleanup code on Python >= 3.11
- Fixed cancelled cancel scopes on asyncio calling ``asyncio.Task.uncancel`` when
  propagating a ``CancelledError`` on exit to a cancelled parent scope
