bedrock: L1 construct for KnowledgeBase is missing the StorageConfiguration parameter in python

[josebagar]

Describe the bug

Required parameter StorageConfiguration for CfnKnowledgeBase appears to have been added to CDK with 2.140.0 (closing #29966 with PR #30037). The python bindings, however, appear to have not been updated, as the parameter is not recognized in the CfnKnowledgeBase L1 construct for Python, defined as below:

    def __init__(
        self,
        scope: _constructs_77d1e7e8.Construct,
        id: builtins.str,
        *,
        knowledge_base_configuration: typing.Union[_IResolvable_da3f097b, typing.Union["CfnKnowledgeBase.KnowledgeBaseConfigurationProperty", typing.Dict[builtins.str, typing.Any]]],
        name: builtins.str,
        role_arn: builtins.str,
        description: typing.Optional[builtins.str] = None,
        tags: typing.Optional[typing.Mapping[builtins.str, builtins.str]] = None,
    ) -> None:

Expected Behavior

The constructor should include the parameter and should create the knowledge base.

Current Behavior

The constructor does not include the parameter. Trying cdk deploy without the parameter results in the following error:

╰─ cdk deploy
