### Issue # (if applicable) Part of: #29186 (comment) ### Reason for this change `aws-ecs-patterns/test/fargate/integ.alb-fargate-service-https-idle-timeout` was failed with certificate error (#29186 (comment)). It is enough to set `idleTimeout` property to test loadbalancer with idleTimeout. `aws-ecs-patterns/test/fargate/integ.alb-fargate-service-https` is also failed with certificate error so I will fix at another PR #29649. ### Description of changes - Rename `aws-ecs-patterns/test/fargate/integ.alb-fargate-service-https-idle-timeout.ts` to `aws-ecs-patterns/test/fargate/integ.alb-fargate-service-idle-timeout.ts` - Remove unnecessary property - Run `yarn integ` ### Description of how you validated changes - Pass integ test ### Checklist - [x] My code adheres to the [CONTRIBUTING GUIDE](https://github.com/aws/aws-cdk/blob/main/CONTRIBUTING.md) and [DESIGN GUIDELINES](https://github.com/aws/aws-cdk/blob/main/docs/DESIGN_GUIDELINES.md) ---- *By submitting this pull request, I confirm that my contribution is made under the terms of the Apache-2.0 license*
