Updater: Fix header margin

* Instead of hardcoding it to 86dp (which was probably fine
  when we didn't have cutouts, calculate the required top margin
  by adding top inset and status bar height and applying it dynamically
* Increase compile and min sdk versions to avoid warnings - we compile
  using the build sdk (33) when building inline anyway
