chore(docs): Fix broken md links (#18384)

Hi, 

I noticed some broken links in the docs and decided to scan for and fix some of them.

There was one that I wasn't able to fix easily in './design/construct-tree.md' which links to some prototype at 
https://github.com/aws/aws-cdk/tree/prototypes/cdk-look

I guess that prototype just doesn't exist anymore.

 For future extensibility, we can however add an `addCapacityProvider` method on the Cluster resource, to allow modifying the cluster CapacityProviders field post-construction.
 
 Another option would be to create a new FargateCluster resource, that would have the two Fargate capacity providers set by default. The main advantage with this alternative would be that it would be consistent with the current Console experience, which sets the Fargate capacity providers for you if you choose the “Networking Only” cluster template via the cluster wizard. The downside is that it would be a more restrictive resource model that would go back on the decision to have a single generic ECS Cluster resource that could potentially contain both Fargate and EC2 services or tasks. Given that we are moving towards more generic versions of ECS resources, this is not a preferable solution. That being said, in the current iteration we can set the Fargate Capacity Providers on the cluster by default, but put them behind a feature flag, which we would be able to remove in the v2 version of the ECS module. Using the feature flag would ensure that there would not be a diff in the generated CFN template for existing customers defining ECS clusters in their stack who redeploy using an updated version of the CDK.
