ci: add SSH server testing to GitHub Actions workflow

- Add a new job `testing-script-error` to the GitHub Actions workflow
- Use `actions/checkout@v4` to check out the code
- Create and run a new SSH server container using `lscr.io/linuxserver/openssh-server:latest`
- Capture the container's IP address and set it as an environment variable
- Add a step to test script errors with `continue-on-error: true`
- Configure the test script to connect to the SSH server and run a command that will fail (`ls /nonexistent`)
