AWS::CodePipeline::Pipeline Fn::GetAtt passes Version as String not Integer

[sheridansmall]

CloudFormation Lint Version

cfn-lint 1.3.2

What operating system are you using?

Windows, Ubuntu

Describe the bug

Using the AWS provided code https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-codepipeline-webhook.html !GetAttWebhookPipeline.Version is called. https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-codepipeline-pipeline.html says it is a number however cfn-lint returns E1010 {'Fn::GetAtt': ['CodePipelineForIntegTest', 'Version']} is not of type 'integer'

Expected behavior

I would expect AWS code samples to pass without errors when tested with cfn-lint given that the code works without error.

This is baffling definition

"TargetPipelineVersion": { "type": "integer" },

Docs are even more odd as they have a pattern on it.

I think what we will have to do is assume that just because the value is of type string that it can still be an integer.
