[native-component-list][android] Fix saving videos to gallery in Came…

…raScreen (expo#25800)

# Why

It wasn't possible to save videos to gallery when using `expo-camera`
example in `ncl`

# How

The file was saved with incorrect extension. Updated the code to use
correct file type.

# Test Plan

- ✅ native-component-list in unversioned expo-go, android 13
- ✅ native-component-list in unversioned expo-go, iOS 17
