 * An AMI builder that uses AWS Image Builder to build AMIs pre-baked with all the GitHub Actions runner requirements. Builders can be used with {@link Ec2RunnerProvider}.

 *
 * You can create an instance of this construct to customize the AMI used to spin-up runners. Some runner providers may require custom components. Check the runner provider documentation.
 *
 * For example, to set a specific runner version, rebuild the image every 2 weeks, and add a few packages for the EC2 provider, use:
 *
 * ```
 * const builder = new AmiBuilder(this, 'Builder', {
 *     runnerVersion: RunnerVersion.specific('2.293.0'),
 *     rebuildInterval: Duration.days(14),
 * });

 *   displayName: 'p7zip',
 *   description: 'Install some more packages',
 *   commands: [
 *     'apt-get install p7zip',
 *   ],
 * }));
 * new Ec2RunnerProvider(this, 'EC2 provider', {
 *     labels: ['custom-ec2'],
 *     amiBuilder: builder,
 * });
 * ```
 *
 * @deprecated use RunnerImageBuilder, e.g. with Ec2RunnerProvider.imageBuilder()
