feat(core): add middleware for getting the wishlist sets upon shared wishlist id changes

[danpadrinom]

Description

This adds a middleware for getting the wishlist sets when the sharedWishlistId has changed. It ensures we are always accessing the updated data from the wishlist sets after creating or deleting a shared wishlist.

Also, the action UPDATE_WISHLIST_SET_SUCCESS was added to the updateSharedWishlistUponItemsChanges middleware and the shared wishlist reducer (result) was adjusted.

Also there is a problem I have just noticed in the implementation, at least in main and I believe v1 also has this problem. In packages/redux/src/sharedWishlists/reducer.ts when the REMOVE_SHARED_WISHLIST_SUCCESS is dispatched, the result slice is not updated which means the getSharedWishlistId selector will keep returning the previous shared wishlist id. Can you take the opportunity to take a look at that case as well, please? If you prefer, you can have it in another PR but that should be tackled. Thank you!

The scope of this PR has been changed as it now adds an action to the updateSharedWishlistUponItemsChanges middleware.
