Description

### Name of the resource

AWS::EC2::Instance

### Resource Name

_No response_

### Issue Description

CloudFormation documentation lists the attribute Id as one of the attributes available in Fn::GetAtt (https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-instance.html#aws-resource-ec2-instance-return-values). However, I get the error "Template error: resource EC2Instance does not support attribute type Id in Fn::GetAtt" when attempting to use it.

### Expected Behavior

The attribute Id should be available to use in Fn::GetAtt.

### Observed Behavior

The attribute Id is not available to use in Fn::GetAtt.

### Test Cases

Tested in the regions us-west-1, us-west-2, us-east-1, and us-east-2.

### Other Details

Research direction

Review the linked AWS CloudFormation documentation and compare it with the reported Fn::GetAtt behavior in us-west-1, us-west-2, us-east-1, and us-east-2. No repository file or test is named; done requires an AWS-side clarification or correction of the documented Id attribute behavior.
