Bug: incorrect docstring on `ImportFrom.level`

[epenet]

According to the docstring the level of a relative import is 0 for absolute imports.
However, in practise it is actually None.

See:

astroid/astroid/nodes/node_classes.py

Lines 2840 to 2846 in 1368be1

	# TODO When is 'level' None?
	self.level: int | None = level # can be None
	"""The level of relative import.
	Essentially this is the number of dots in the import.
	This is always 0 for absolute imports.
	"""

I would suggest that the TODO is removed and that the docstring is ajusted accordingly.

python -c "from astroid import __pkginfo__; print(__pkginfo__.version)" output

3.2.4
