Note for follow-up: We should check canInsertBlockType here as well. Disabling the block from Preferences results in broken behavior.

Not sure if we can do that. What If some block disables footnotes to be inserted as inner blocks? That doesn't mean footnote anchors can't be inserted.

So maybe what we should check here is well is just if footnotes is registered at all? But I guess the preference doesn't unregister it.

We'll need to check if the footnotes block is disabled; it doesn't have to be canInsertBlockType.

Looks like that is in the editPostStore, which would create a dependency on the edit-post packages for block-library. 🤔

Added a registration check in 185c7b3, but that doesn't fix the preferences problem. Not sure if we should depend on the edit post package. Maybe the footnotes block doesn't belong in the block library package. Or is it fine to add the dependency?
