Documentation typo: Models in Graphnet Instantiating a StandardModel

[CamphynR]

On the documentation page (https://graphnet-team.github.io/graphnet/models/models.html#) under "Models in Graphnet Instantiating a StandardModel" in the code snippet it reads:

backbone = DynEdge(
    nb_inputs=detector.nb_outputs,
    global_pooling_schemes=["min", "max", "mean"],
)

which should be:

backbone = DynEdge(
    nb_inputs=graph_definition.nb_outputs,
    global_pooling_schemes=["min", "max", "mean"],
)
