Incorrect Usage. flag provided but not defined: -version

**Describe the bug**

When running `git-xargs --version` gives the error
> Incorrect Usage. flag provided but not defined: -version

**To Reproduce**

```shell
[12/04/23 1:43:34] ➜ github_config git:(master) ✗ go install github.com/gruntwork-io/git-xargs@v0.1.5
[12/04/23 1:45:07] ➜ github_config git:(master) ✗ git-xargs --version
Incorrect Usage. flag provided but not defined: -version

Usage: git-xargs [--loglevel] [--github-org] [--draft] [--dry-run] [--skip-pull-requests] [--skip-archived-repos]
[--repo] [--repos] [--branch-name] [--base-branch-name] [--commit-message] [--pull-request-title]
[--pull-request-description] [--reviewers] [--team-reviewers] [--seconds-between-prs] [--max-pr-retries]
[--seconds-to-wait-when-rate-limited] [--no-skip-ci] [--keep-cloned-repositories] [--help] command [options] [args]

git-xargs is a command-line tool (CLI) for making updates across multiple Github repositories with a single command.

Commands:

help, h Shows a list of commands or help for one command

ERROR: flag provided but not defined: -version
[12/04/23 1:45:12] ➜ github_config git:(master) ✗
```

This also happens when running
```shell
go run github.com/gruntwork-io/git-xargs@v0.1.5 --version
```

**Expected behavior**

I would expect to get the version of git-xargs.

**Nice to have**
