Research direction
This feature request asks for adding support for Playwright 4.0 and 5.0 in the @amzn/synthetics playwright Python package. The implementation likely involves updating the runtime definitions in the AWS CDK codebase, specifically in the `aws cdk.aws synthetics` module, to include new runtime constants like `SYNTHETICS NODEJS PLAYWRIGHT 4 0` and `SYNTHETICS NODEJS PLAYWRIGHT 5 0`. The issue currently has one assignee, indicating it is claimed, so contributors should coordinate if interested. Refer to the existing implementation for version 3.0 as a template.
