Gracefully handle failure to fetch tags

This tool will automatically run `git fetch --tags` before starting. Sometimes, however, this step can fail, particularly in the case where a tag was force-pushed. This prevents the developer from being able to create a release.

This tool should detect when fetching tags fails and suggest that the user run `git fetch --tags --force` manually to resolve it (or perhaps offer the option to run it automatically).

Start at the release-startup path that runs `git fetch --tags`, and inspect how fetch failures are currently reported. Reproduce a failed tag fetch, then make the failure actionable by suggesting `git fetch --tags --force` or an automatic retry; verify that successful fetches and failure handling both behave as expected.
