Add errata supporting changes to position: static (#1434)

Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1434

X-link: https://github.com/facebook/react-native/pull/41130

I will use this errata to gate my changes that actually make position: static behave like the web. We have future plans to make position: relative the default again but users could still have declared certain nodes as position: static, so I think this is needed regardless.
