bug: failed to set disable_auto_update option

**Describe the bug**

disable_auto_update option does not work.

**To Reproduce**

1. run container

```
docker run -it -e token="******" -e owner="kuju63" -e repo_name="github-runner" -e runner_name="sample" -e disable_auto_update="1" github-runner:latest
```

but error occurred.

```
Unrecognized command-line input arguments for command run: 'disableupdate'. For usage refer to: .\config.cmd --help or ./config.sh --help
An error occurred: Not configured. Run config.(sh/cmd) to configure the runner.
```

**Expected behavior**

Error does not be occurred.

**Runtime environment (please complete the following information):**

- Container runtime: Docker
- Version: 0.5.4
- GitHub: GitHub.com
- GitHub Version (GitHub Enterprise Server only): [e.g. 3.0.4]

Start with the Docker run command and the disable_auto_update option, then inspect how the container passes options to config.sh or config.cmd. Reproduce the issue with the provided command and confirm that configuration completes without the disableupdate argument error.
