No more picking out version numbers by hand! Now we let the script do
it:
```
$ ./codex-rs/scripts/create_github_release --dry-run --publish-alpha
Running gh api GET /repos/openai/codex/releases/latest
Running gh api GET /repos/openai/codex/releases?per_page=100
Publishing version 0.31.0-alpha.3
$ ./codex-rs/scripts/create_github_release --dry-run --publish-release
Running gh api GET /repos/openai/codex/releases/latest
Publishing version 0.31.0
```
