Add syntax for multiple source and synth actions for CodePipeline

[geovin89]

const pipeline = new CodePipeline(this, 'Pipeline', {
      pipelineName: 'MyPipeline',
      synth: new ShellStep('Synth', {
        input: CodePipelineSource.gitHub('OWNER/REPO', 'main'),
        commands: ['npm ci', 'npm run build', 'npx cdk synth']
      })
    });

Can you add example for code pipelines that has multiple input sources (possibly with different language, like CDK code in typescript and lambda in java)?

Can anyone provide an example as a comment to this? I am looking for how to actually achieve this.
