AccordionField not possible to be folded when the page loads

[Ducica]

Package version (if known): 2.8.4

Describe the bug

Since defaultActiveIndex is removed (seems to be recent change), it is no longer possible to control via prop if the accordion will be folded or not when the page loads. The activeIndex is internal component state into which we cannot plug in any way. Normally, we need to keep some accordions open on page load and others folded. This should definitely be programmable via props like it used to be.

Steps to Reproduce

Use the component and try to control the accordion initial state via props.

This has been annoying for us as well and would be great to get fixed @Ducica

[Ducica]

Okay, I can do it, I am not sure if I need to get a go ahead from @ntarocco first?

Anyone is always free to make PRs. When they get merged is another question. Having the ability to customize tab opening again is very much a desired feature, as long as you don't break accessibility.
