Change React Native Version import to the one from Platform

[svbutko]

📢 Type of change

• Bugfix
• New feature
• Enhancement
• Refactoring

📜 Description

The import for selection of React Native version, both for type and value happens via JS constant, while there's an documented way to get it from Platform: https://reactnative.dev/docs/platform#constants

It's also available in 0.65 which makes it work for all versions:

💡 Motivation and Context

While working with other repos than react-native like react-native-tvos or react-native-web with certain TS configs, there are issues like this one:

node_modules/@sentry/react-native/dist/js/utils/rnlibrariesinterface.d.ts:1:37 - error TS7016: Could not find a declaration file for module 'react-native/Libraries/Core/ReactNativeVersion'. '/Users/**/zattoo/aurora/node_modules/react-native/Libraries/Core/ReactNativeVersion.js' implicitly has an 'any' type.
  If the 'react-native-tvos' package actually exposes this module, try adding a new declaration (.d.ts) file containing `declare module 'react-native/Libraries/Core/ReactNativeVersion';`

1 import type { version as RNV } from 'react-native/Libraries/Core/ReactNativeVersion';

This PR solves this import issue
