Support aws:ssm:integration data type

[thomasklinger1234]

Summary

According to the documentation, the AWS::SSM::Parameter resource does not support the data type aws:ssm:integration which is required to create webhook integrations.

Desired Result

I can create the following resource:

MyIntegration:
  Type: AWS::SSM::Parameter
  Properties:
    Name: /d9d01087-4a3f-49e0-b0b4-d568d7826553/ssm/integrations/webhook/test
    Type: String
    DataType: "aws:ssm:integration"
    Value: |
      {"url": "<some-url>", "description": "webhook URL"}

Currently, we need to work around this limitation by creating it via script.
