BUG: After setting model_diagram=False on instantiated model card, the diagram is still shown

[BenjaminBossan]

It would be nice to be able to disable the model diagram after the model card has been instantiated by setting the attribute to False. However, this does not happen:

from sklearn.dummy import DummyClassifier
from skops import card

clf = DummyClassifier()
c = card.Card(clf)
print(c.model_diagram)  # True

c.model_diagram = False
c.render()  # still contains the model diagram

It is not difficult to work around this, as a user I can simply do:

c.delete("Model description/Training Procedure/Model Plot")

but it's inconvenient.
