Togglebuttons with multiple attribute returns array of selected strings when on-value is set

Reproduction

Describe the bug

Expected result Similar to Standalone Toggle when off-value=false and on-value=true

{
  "pizza_toppings": {
    Pepperoni: true,
    Sausage: true,
    Mushroom: false,
    Olives: false,
  }
}

Instead of Perhaps return this when on-value=null to also support array of selected strings?

{
  "pizza_toppings": [
    "Pepperoni",
    "Sausage"
  ]
}

@Rednas83 This is a little bit too much of a departure from the way preexisting inputs with the multiple prop and array of values currently work (checkbox, dropdown-family inputs, transferlist). I don't think this is something we'll be supporting.

Idk For me it's confusing that a toggle button is returning a string instead of a boolean. Why not support both scenarios to make it more universal? It think it can be done without any breaking changes by adding support for the off-value and on-value attributes. Or perhaps with a new attribute. Something like: Multiple Returns array of strings Bool Returns objects of booleans

I wrote a small helper function as a workaround to get from array to object which also works for me but I would prefer a native solution

I'll reopen the issue. Perhaps someone else on the team may want to comment.
