Subject: [PATCH] Let -v respond with gem version instead of 'unknown'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is what was printed before:
```
➜  dead_end git:(main) ✗ dead_end --version
dead_end: version unknown
```

Now we get the actual gem version in the output.
