@aws-cdk/integ-tests-alpha:DescribeUserPool

### Describe the bug

I am making an assertion as follows
`const assertion1 = integ.assertions
.awsApiCall('CognitoIdentityServiceProvider', 'describeUserPool', {
UserPoolId: 'ap-southeast-1_1234567'
})
.expect(ExpectedResult.objectLike({
UserPool: {
Id: 'ap-southeast-1_1234567'
},
}));`

When I run `npm run integ-test`
I get the error
`CREATE_FAILED | Custom::DeployAssert@SdkCallCognitoIdentityServiceProviderde | CognitoStackTest/DefaultTest/DeployAssert/AwsApiCallCognitoIdentityServiceProviderdescribeUserPool31f29c4a94406a13295f446784a03bfb/Default/Default (AwsApiCallCognitoIdentityServiceProviderdescribeUserPool31f29c4a94406a13295f446784a03bfb) Response object is too long.`

### Expected Behavior

The CognitoStackTestDefaultTestDeployAssert stack needs to successfully deploy.

### Current Behavior

I get the error
`CREATE_FAILED | Custom::DeployAssert@SdkCallCognitoIdentityServiceProviderde | CognitoStackTest/DefaultTest/DeployAssert/AwsApiCallCognitoIdentityServiceProviderdescribeUserPool31f29c4a94406a13295f446784a03bfb/Default/Default (AwsApiCallCognitoIdentityServiceProviderdescribeUserPool31f29c4a94406a13295f446784a03bfb) Response object is too long.`

### Reproduction Steps

Create an assertion using the following code

`const assertion1 = integ.assertions
.awsApiCall('CognitoIdentityServiceProvider', 'describeUserPool', {
UserPoolId: 'ap-southeast-1_1234567'
})
.expect(ExpectedResult.objectLike({
UserPool: {
Id: 'ap-southeast-1_1234567'
},
}));`

Start with the integ.assertions.awsApiCall('CognitoIdentityServiceProvider', 'describeUserPool', ...) entry point and reproduce the issue with npm run integ-test using the assertion shown. Trace why the describeUserPool response exceeds the deployment limit; done means the CognitoStackTestDefaultTestDeployAssert stack deploys successfully with the expected UserPool.Id assertion.
