(aws-rds): Python typing issue with EngineVersion

What is the problem?

There is a typing error with RDS EngineVersions in the Python version of the CDK.

Expected type 'AuroraMysqlEngineVersion', got '() -> AuroraMysqlEngineVersion' instead 

I copied this code directly from the example in the docs: https://docs.aws.amazon.com/cdk/api/v1/python/aws_cdk.aws_rds/README.html

Reproduction Steps

1. Clone https://github.com/blimmer/cdk-bug-reports
2. Check out the python-db-type-issue branch
3. Open the code in a Python IDE (e.g., PyCharm)
4. Open the python_cdk/python_cdk_stack.py file.

You’ll see the type error:

What did you expect to happen?

I expected the example from the official documentation (https://docs.aws.amazon.com/cdk/api/v1/python/aws_cdk.aws_rds/README.html) to not have any errors.

What actually happened?

A type error was displayed:

Expected type 'AuroraMysqlEngineVersion', got '() -> AuroraMysqlEngineVersion' instead
