No examples for client-guardduty `FindingCriteria`

[tomchiverton]

Describe the issue

No examples of filtering, here is one I would have found useful

		{
		DetectorId: _detectorId,
		FindingCriteria: {
		    Criterion: {
		      "type": {
		      	"Eq":["Object:S3/MaliciousFile"]
		      }
		  }
		}
```
