fix: change getToggleButtonProps typing to support div

[drewbrend]

What:

getToggleButtonProps should support HTMLButtonElement or HTMLDivElement props

Why:

In the downshift docs, useSelect recommends applying getToggleButtonProps to a div element but getToggleButtonProps specifies its options are specific to a button. This works fine, unless you want to provide options to getToggleButtonProps that are unique to a div element, in my case I ran into this when providing a ref to my HTMLDivElement - this conflicted because Ref<HTMLDivElement> is not applicable to Ref<HTMLButtonElement>

How:

Simply added | HTMLDivElement to its type.

Thanks @drewbrend for the fix! I will make sure to address it in #1482. The reason is that only the UseSelectToggleButtonPropsOptions should have this change, which is going to most probably be only HTMLElement, since someone may want to use anything else other than a div. We are using a div, aria uses a div in their example, but that's not really a hard requirement. It most probably should not be a button, since button with a role of combobox is not really correct, but it might not be a div anyway.

And it's going to be a breaking change, so expect this to arrive in v8.
