ci: add multi-server support to CI workflow

- Add a new job `multiple-server` to the GitHub Actions workflow
- Configure the job to run on `ubuntu-latest`
- Add steps to checkout code, add public and private keys to environment variables, and create two new SSH servers using Docker
- Update the `host` configuration to include both new SSH servers
- Remove the `port` configuration
- Replace the command `ls -lah` with `whoami`
- Remove the `use_insecure_cipher` configuration
