cli: Cloud assembly schema version mismatch with latest versions

Describe the bug

After upgrading everything to latest versions (python libs: 1.154.0, cli version: 2.22.0 (build 1db4b16)), i get the following error:

This CDK CLI is not compatible with the CDK library used by your application. Please upgrade the CLI to the latest version.
(Cloud assembly schema version mismatch: Maximum schema version supported is 17.0.0, but found 18.0.0)

Expected Behavior

No error.

Current Behavior

Getting error after updating everything to latest.

Reproduction Steps

1. mkdir cdk-repro
2. cd cd cdk-repro/
3. cdk init app --language python
4. rm -rf .venv/
5. python3 -m venv .venv
6. edit requirements.txt to use aws cdk v1:

   aws_cdk.core
   

7. edit app.py to use aws cdk v1:

   #!/usr/bin/env python3
   import os
   
   from aws_cdk import core as cdk
   
   ...
   
   

8. edit cdk_repro_stack.py:

   from aws_cdk import core as cdk
   
   class CdkReproStack(cdk.Stack):
   
       def __init__(self, scope: cdk.Construct, construct_id: str, **kwargs) -> None:
           super().__init__(scope, construct_id, **kwargs)

See the official docs: https://docs.aws.amazon.com/cdk/v2/guide/migrating-v2.html

1. update requirements.txt:

old	new
aws_cdk.core aws_cdk.aws_iam	aws-cdk-lib

1. update imports

old	new
from aws_cdk import ( aws_iam as iam, core as cdk, )	from constructs import Construct from aws_cdk import ( Stack, CfnOutput, aws_iam as iam )

1. update cdk.json (remove content of “context”)
2. remove the python venv, recreate it and do a pip install
3. i also had to rerun cdk-boostrap on all accounts/regions

We had a mistake in our release process, which caused a difference in commits between the latest v1 and v2 to be released. Our apologies.

2.23.0 supports the latest cloud assembly format.
