Support Platform.constants['Release']

[jbcullis]

Summary

Platform.constants['Release'] returns undefined.

Motivation

As part of our logging strategy, we report on user OS version.
I can see a property 'osVersion' however this returns 15 which I would have expected 10.x.x

@chrisglein @chiaramooney few questions here

1. Is major.minor.build.revision the desired string here? For example:

2. Even though specs dir is now renamed deprecated, it is still proper to alter the spec file in [src/private/specs/modules/NativePlatformConstantsWindows]?(https://github.com/microsoft/react-native-windows/blob/main/vnext/src-win/src/private/specs_DEPRECATED/modules/NativePlatformConstantsWindows.js)
