[4.x]: Removing shipping address from an order (via the REST API) does not work

[freder]

What happened?

setting shippingAddressId and shippingAddress to null (in the commerce/cart/update-cart payload) has no effect.
if a shipping address was set before, it will not have been removed.

---

also somewhat related: I noticed that when removing the shipping address via the admin, the address gets set to null but somehow shippingAddressId keeps its value.

in 4.2.9 we added the following params accepted by commerce/cart/update-cart:

clearShippingAddress
clearBillingAddress
and clearAddresses

Hope that helps.

from what I can tell this isn't mentioned anywhere in the docs.
I would have expected it here.
