Check if CallbackUrls can be omitted when creating a user pool client in identity provider tests

[cPu1]

The integration test for identity provider (integration/tests/identity_provider/identity_provider_test.go) sets some additional fields like CallbackUrls in the call to CreateUserPoolClient that may not be required. Revisit those fields and remove those that deem unnecessary, while ensuring the tests still pass.

@cPu1 can you add more details of the tests in question here? which test needs to be updated?

Low prio for now, worth revisiting in future at some point
