codepipeline-actions: RuntimeError: Error: The 'account' property must be a concrete value

### Describe the bug

I am seeing `RuntimeError: Error: The 'account' property must be a concrete value` during `cdk synth`

### Expected Behavior

`cdk synth` succeeds

### Current Behavior

`cdk synth` fails with `RuntimeError: Error: The 'account' property must be a concrete value`

During `cdk synth --profile ` I get:
```
(.venv) (py311) PS C:\Users\Subhashis\Desktop\DHCDK> cdk synth --profile
123456789
ap-south-1
jsii.errors.JavaScriptError:

The above exception was the direct cause of the following exception:

Start by reproducing the failure with app.py and trace DhAppPipelineStack.create_deploy_stage in dh_app_pipeline_stack.py, especially the EcsDeployAction setup and the account and region values printed there. Compare the deploy action inputs with the AWS CDK CodePipeline and ECS action behavior, then run cdk synth; done means synthesis succeeds without the concrete-account RuntimeError for DeployBeta and DeployProd.
