BUG: Fix PySide6 compatibility

[larsoner]

So this is a problem:

$ python -c "from IPython.external.qt_for_kernel import QtGui; print(QtGui)"
<module 'PySide6.QtPrintSupport' from '/home/larsoner/python/virtualenvs/base/lib/python3.12/site-packages/PySide6/QtPrintSupport.abi3.so'>

The source file for qt_for_external says that it's kept for backward compat, so perhaps no surprise it doesn't work. I don't see any reason we need to triage based on being in ipython or not, though, given everything else comes from qtpy earlier anyway.

@tkoyama010 you added this in https://github.com/pyvista/pyvistaqt/pull/40/files#diff-bcab1285ff8ba2b1a25b18d87cd02a09eca4194b83196ba0c2b7939c76393d01R65, any recollection why it was necessary?

... I suggest we merge this and cut a bugfix 0.11.1 for this. I added a release.yml to remove all the dependabot PRs from the autogenerated release notes because they're unhelpful.

I also opened ipython/ipython#14463 but I don't think we should need IPython for this in any case

It is not particularly impressive and can be removed. I apologize for not leaving a clear comment.
