Adjust version parsing in release scripts, fix release dry runs in CI (#43568)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/43568

Fixes to restore passing CI checks on main after D55027120.

- Widen validation checks in version utils to accept `0.x.x` (as opposed to `0.[not-'0'].x`).
- Use `tag: test` instead of `tag: latest` for dry run job params.
