Describe the bug

  MyS3Bucket:
    Type: 'AWS::S3::Bucket'
    Properties:
      AccessControl: '{{resolve:ssm:${AWS::AccountId}/${AWS::Region}/ac}}'

result in

E1050 ['resolve', 'ssm', '${AWS', '', 'AccountId}/${AWS', '', 'Region}/ac'] is too long (4)
E1050 '' does not match '\\d+'

Expected behavior

I thinking : inside ${} should be ignored while checking this rule.
