Convert matplotlib gui name in enable_gui (#14451) This is a bug that I discovered whilst dealing with matplotlib/matplotlib#28332. The change here is in `TerminalInteractiveShell.enable_gui` which needs to convert a gui of `macosx` from Matplotlib into `osx` in IPython. It reuses the converter function created in #14420. I've added a test that uses `enable_gui` and raises an exception before this PR but passes with it. The remainder of the changes are formatting changes from `pre-commit`.

Implement `IPython.utils.io.Tee.isatty` (#14460) A lot of libraries would call `sys.stdout.isatty()`, but `IPython.utils.io.Tee` does not implement `isatty`. Let's add the method to avoid errors.

fixed honoring custom repr for NamedTuple if assigned by partialmethod (#14466) Fixes #14465. - added test `test_custom_repr_namedtuple_partialmethod`

switch to safe_getattr

bugfix for call to structured_traceback (#14453) Calls to `structured_traceback` take the exploded 3-tuple of `*sys.exc_info()` as separate arguments, so we don't want to pass the 3-tuple as one argument. This should fix some of the symptoms people are seeing in https://github.com/ipython/ipython/issues/12831 Test plan: local editable install, seems to work OK. Haven't tried to repro the problem from the linked issue but this change probably can't hurt. From https://github.com/ipython/ipython/pull/14454, which is just an empty commit, I see the same test failures as in this PR's "Run Downstream tests" job: https://github.com/ipython/ipython/actions/runs/9375565881/job/25813901627?pr=14454 So I'm guessing it's not related to the change in this PR.
