Upgrade react-native - Githubissues

Task Upgrade react-native to the latest stable version.

TODOs:

[ ] Upgrade react-native to the latest stable version. If there are to many changes, feel free to split it up into multiple upgrades (e.g. to 0.71 and then to 0.73).
[ ] Upgrade react-native-header-buttons requiring react-native v0.71: https://github.com/vonovak/react-navigation-header-buttons/releases/tag/v11.0.0
[ ] Upgrade react-native-reanimated, react-native-gesture-handler and react-native-screens to latest which are blocked by this
[ ] Uncomment the findAllByRole section in ImageCarousel.spec.tsx and make it work again (it seems like react-native is migrating from accessibilityRole to role which let the test fail)
[ ] Remove the patch for react-native-camera that was added in https://github.com/digitalfabrik/lunes-app/pull/404 because of deprecated prop-types (if #873 isn't done before)
[ ] remove workaround in podfile (https://github.com/facebook/react-native/issues/37748)

Additional context Possibly blocked by #1012. The upgrade helper might help: https://react-native-community.github.io/upgrade-helper/?from=0.70.15&to=0.73.6

Related: #983.
