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:
https://reactnative-archive-august-2023.netlify.app/docs/0.65/platform#constants

💡 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

💚 How did you test it?

Hi @svbutko,
thank you for the fix. Excuse the long waiting time, I was OoO.

It definitely make sense to use the public documented export instead of the internal lib.

Could you check why yarn test fails after the change. I've already added changelog, but we need the tests to succeed to merge the change.

Hi @krystofwoldrich
No problem at all!

Checked the tests, and added a fix for potential missing constants (e.g. testing or going beyond supported platforms)

Sometimes there's a failing stalltracking.background.test.ts test: Stall tracking should set _isBackground to false, update _lastIntervalMs, and call _iteration when state is active and _timeout is not null but it's not related to this PR and it's floating

Thank you @svbutko!

It looks good now. 🚀
