fix(Android): modify the decorFitsSystemWindow parameter in setNaviga…

…tionBarHidden (#1988)

## Description

Currently when user tries to change the appearance of the navigation bar
(using navigationBarHidden / navigationBarColor props) the content of
the screen jumps to the place that does not respect safeAreaView. This
PR fixes it by removing `decorFitsSystemWindow` declaration, as it
breaks the interface by matching it to `fit system window`.

Resolves #1719.

## Changes

- Removed `decorFitsSystemWindow` call from `ScreenWindowTraits.kt`

## Checklist

- [X] Ensured that CI passes
