Subject: [PATCH] Made npm deployment to be independent of git tags cache

Summary:
Fixes npm deployment script as in https://circleci.com/gh/facebook/react-native/6745.

Example situation:
- admin is ready to release 0.26.0
- admin adds tag v0.26.0 and pushes to origin
- Circle CI build fails because of code error
- admin cherry-picks a fix and tags v0.26.0 again and pushes to origin
- Circle does not update local tag v0.26.0 because it already has it cached, compiles the code but fails to deploy to npm because v0.26.0 is not on branch HEAD from Circle point of view

The previous version of the script was checking the tags on current commit as well but it used the local branch tags.
This change fetches tags from `origin` fresh and allows us to redeploy the same version multiple times.
Closes https://github.com/facebook/react-native/pull/7619
