• Added stac-browser to integration build test

Let's add a STAC Browser construct to the integration test app so we test the deployment on each PR!

Will have to take a closer look into the initial deployment failures in the health check, but it seems to have passed this time

Not entirely sure if the memory issue is reproducible exactly, when we're tearing down the stack each time, but on fresh deployments, the stac-browser deploys successfully in little to no time.

I've also added the option for auto_delete_objects on the stac-browser bucket - great for our ephemeral stack and user test environments where they may want to delete and redeploy stacks without manually going to empty and delete the bucket.
