[AWS::SSM::Document] - [Enhancement] - Implement `Drift Detection`

### Name of the resource

AWS::SSM::Document

### Issue Description

`AWS::SSM::Document` is not appearing in drift detection results, despite being documented as a resource being supported for drift detection:

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/resource-import-supported-resources.html

### Expected Behavior

`AWS::SSM::Document` included in drift detection results.

### Observed Behavior

`AWS::SSM::Document` is NOT included in drift detection results.

### Test Cases

```
Document:
Type: AWS::SSM::Document
Properties:
Name: "Test"
DocumentType: "Command"
Content:
schemaVersion: "2.2"
description: "Test"
mainSteps:
- action: aws:runShellScript
name: runCommands
precondition:
StringEquals:
- platformType
- Linux
inputs:
runCommand:
- 'Echo "CloudFormation is better than CDK"'
```

Start with the supplied AWS::SSM::Document template and reproduce drift detection using the linked CloudFormation documentation as the reference. Compare the resulting drift report with the expected inclusion of AWS::SSM::Document; done means the resource appears in drift detection results with its drift status reported.
