Fix: eliminate cognito idp from CognitoUserPoolClient

[taniguchiiqqq]

Bug Description

When I addressed this issue #134, the solution unintentionally allowed the userPoolClient to use Cognito IDP.

Expected Behavior

This test code should be passed.

template.hasResourceProperties("AWS::Cognito::UserPoolClient", {
	SupportedIdentityProviders: ["Google"],
});

Additional Context

Any other context about the problem.
