(CLI): hotswap still does not wait for Lambda code to be fully updated

[MikeFHay]

Describe the bug

I own a Lambda within a VPC. When I run cdk deploy --hotswap --method=direct --require-approval=never $stackName, and run tests against the deployed Lambda, I see that the previous version of the lambda code is run. Waiting a minute and running the test again correctly runs against the updated code. This issue was supposedly fixed in #18386 , but I am still seeing the issue in CDK 2.45.0. According to that issue the delay is particularly large for Lambdas within VPCs, so this may not be noticeable on other Lambdas.

Expected Behavior

After cdk deploy --hotswap exits, all future calls to the deployed Lambda should see the new code.

Current Behavior

After cdk deploy --hotswap exits, immediately calling the deployed Lambda executes the previous code.

Reproduction Steps

Make an observable change to a Lambda within a VPC, run cdk deploy --hotswap --method=direct --require-approval=never $stackName, immediately call the lambda, and observe that the code change is not in effect. Wait and call again to confirm that the code change is eventually present.

Actually seems like this happens without --hotswap too.

Without --hotswap, this would do a full CloudFormation deployment. Are you observing the same behavior there?

If you can reproduce this, can you do a describe of the lambda immediately after updating it and show the status? If the status is success and yet the code is not updated, there's unfortunately nothing we can do here and this would be an issue for the Lambda team.
