refactor: use side-effect import declaration to ensure TurboModule ge…

…ts loaded (#2468)

## Description

We want to ensure that the tubomodule spec gets loaded & executed
and at the same time we don't want it exported. 

This syntax should ensure it! [MDN docs
link](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import#import_a_module_for_its_side_effects_only)

## Changes

Change export to side effect import!

## Test code and steps to reproduce

Run FabricExample on Android & see that the underneath screen does not
disappear when popping a screen.
