[Accordion] How to expand all items without hard coded default-value?

[BuptStEve]

I'm building a new ui-lib on top of reka-ui.
I'm wondering maybe we can just add a prop like defaultExpandAll to expand all items without hard coded default-value prop.

Line 13 in 1e0670d

extends Omit<CollapsibleRootProps, 'open' | 'defaultOpen' | 'onOpenChange'> {

Maybe we don't omit defaultOpen?

  :defaultOpen="rootContext.defaultExpandAll"
