Hi @armujahid,

Thanks for raising this feature request!

You are correct, the AWS Synthetics runtimes syn-python-selenium-5.0 and syn-python-selenium-5.1 are currently missing from the AWS CDK synthetics.Runtime options.

The necessary change involves adding these new runtime versions as static members to the Runtime class in packages/aws-cdk-lib/aws-synthetics/lib/runtime.ts, similar to how existing runtimes like SYNTHETICS_PYTHON_SELENIUM_4_1 are defined. Corresponding tests would also need to be added.

Since you mentioned you might be able to implement this, we would gladly welcome a Pull Request for this feature!

Let us know if you plan to work on this or have any questions!
