get localstorage support (#2190)

[dinhlongviolin1]

Resolve #2190

localStorage.setItem and localStorage.removeItem can be used directly on the browser console to test out the feature

from taipy.gui import Gui, get_local_storage


def button_click(state):
    print(get_local_storage(state, "TaipyClientId")) # would return str | None
    print(get_local_storage(state, "TaipyClientId", "hey")) # would return dict

Gui("<|Click me|button|on_action=button_click|>").run()

Not sure about this local storage API redéfinition in the browser
Way to invasive for my taste
And I'm not sure a security audit would appreciate

[FabienLelaquais]

I would like to improve the doc a little bit before you actually merge.
Let's do that together if that works for you.

[FabienLelaquais]

Line skip here.

Can this be called anytime in the app life cycle?

I suspect we should add more details on invoking this API (with the complexity of the keys type).

[dinhlongviolin1]

i have not tested every case but it is very early on, only after the state id is initialized.

[FabienLelaquais]

Line skip.

Explanations are pretty weak. Let's spend some time together on this one.

[dinhlongviolin1]

i am open to any proposal to the doc
