Add an example of setting up HTTPS on ApplicationLoadBalancedFargateService

An example showing the recommended way of enabling HTTPS on an `ApplicationLoadBalancedFargateService`.

### Use Case

I am having issues enabling HTTPS in my `ApplicationLoadBalancedFargateService`. I have been digging many issues and StackOverflow issues and trying to wrap my head around all the possible configurations. Should I add `certificate` to the service directly? Then I need to set up domains. Should I create an entirely new `ApplicationLoadBalancer`? Should I add a listener for 443 in the `loadBalancer` property?

There is no clear path and the documentation is somewhat inconsistent as to how to do it.

* [X] :wave: I may be able to implement this feature request
* [ ] :warning: This feature might incur a breaking change

---

This is a :rocket: Feature Request

Start by locating the documentation or examples for ApplicationLoadBalancedFargateService and review the existing HTTPS configuration guidance. Confirm the recommended setup with the project’s current APIs, then add a focused example that resolves the certificate, domain, load balancer, and port questions; done means the example is clear and consistent with the surrounding documentation.
