Get useInnerBlocksProps hook out of experimental status

[fabiankaegy]

What problem does this address?

The useInnerBlocksProps hook was added in October 2020 via #25633 as an experimental hook. Since its release, a few bugs have appeared (#34120, #30408, #29513, #29482, #29036, #14242) but, in general, no breaking feedback has been received. However, this might be either because the hook version is very stable or because of a lack of wider testing.

What is your proposed solution?

We should consider moving the useInnerBlocksProps out from experimental as the next step towards wider adoption and as a means to receive more organic feedback from users.

Alternate options

If we feel it is not ready to be marked as a stable API I think we would benefit from adding some experimental documentation for plugin authors etc to test this hook and provide feedback.

@ellatrix Since you are the brain behind the hook implementation do you see any reason why the hook would not be ready?

Would love to get your thoughts on this :) Thanks in advance!

There's a PR that's been around for a while: #26031. I'll rebase it.

Very excited for this. I've wanted to use it but I refrain from using experimental APIs since they will break when experimental status is removed.
