Wrongly assigned generics for `networkx.Graph`

[lkct]

In the current version of typeshed, networkx.Graph is defined as a generic type:

typeshed/stubs/networkx/networkx/classes/graph.pyi

Line 11 in 11c7821

_Node = TypeVar("_Node", bound=Hashable)

typeshed/stubs/networkx/networkx/classes/graph.pyi

Line 30 in 11c7821

class Graph(Collection[_Node]):

However, networkx.Graph is not a generic type at all:
https://github.com/networkx/networkx/blob/1660ac379a1c10e3d413760785dbc5cd2186a125/networkx/classes/graph.py#L71
and there'n no explicit __class_getitem__ in that class.

Therefore, when I use this type as hinted by the stubs, I get runtime error TypeError: type 'Graph' is not subscriptable.

I checked for similar issues, including #14389 and #12186, but none of them seem to address this problem.
