nbsite currently does not work with ipykernel >= 7.0

[hoxbro]

Pinned in #348.

A lot of changes have been made in 7.0, but the culprit is what we are doing around these, the execute here:

nbsite/nbsite/nbbuild.py

Lines 85 to 107 in b8f22c5

	class ExecutePreprocessor1000(ExecutePreprocessor):
	"""Sigh"""
	_ipython_startup = None
	@property
	def kc(self):
	return self._kc
	@kc.deleter
	def kc(self):
	del self._kc
	@kc.setter
	def kc(self, v):
	self._kc = v
	if v is not None and self._ipython_startup is not None:
	self._kc.execute(
	self._ipython_startup,
	silent=False,
	store_history=False,
	allow_stdin=False,
	stop_on_error=True,
	)

To recreate the problem, you should be able to have no untracked files in site/ and then run the following command: pixi run -e docs install && pixi run docs-build

It only happens when running Sphinx in parallel, and it freezes when you Ctrl+C it give this output:
