Important

1. If we hide the tab bar from the beginning and then show it later, appearance configuration doesn't seem to work on selected tab until you change the tab and go back. This seems to be a native bug as under certain circumstances it is reproducible in bare UIKit app but we should investigate this further. I added a ticket on our board: https://github.com/software-mansion/react-native-screens-labs/issues/516.

2. Animating tab bar visibility change is also possible starting from iOS 18. I decided not to implement this now as we need to prevent initial animation/think of different API for visibility changes.
