Fetch Github tags in the publish-release job (#46131)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/46131

React native 0.75.0, 0.75.1 and 0.75.2 has been published to NPM without the latest tag, despite the tag being on the commit.

When debugging why that's happened, I realized that we were not downloading the tags when checking out the repo.

This change fixes that.
