Failing tests in `solid-contrib/solid-crud-tests`

During the testing process on https://solid-crud-tests-example-1.solidcommunity.net, several tests have unfortunately not yielded successful results.

The tests in question specifically pertain to the Notification and Storage categories. To provide a concise overview:

FAIL  test/surface/notifications.test.ts
Notifications
When overwriting plain text with plain text using PUT
  ✕ WPS  insecure websockets-pubsub advertised using Updates-Via Link header (11 ms)
  ✓ WPS  emits insecure websockets-pubsub on the resource (1 ms)
  ✕ SECURE_WEBSOCKETS  secure websockets advertised using server-wide or resource-specific Link header (3 ms)
  ✓ SECURE_WEBSOCKETS  emits secure websockets notification on the resource
  ✕ WEBHOOKS  webhooks advertised using server-wide or resource-specific Link header (1 ms)
  ✕ WEBHOOKS  emits webhook notification on the resource (1 ms)
 

FAIL  test/surface/fetch-pod-root.test.ts
Alice's storage root
  ✕ is an ldp BasicContainer (3 ms)

Start by running the failures in test/surface/notifications.test.ts and test/surface/fetch-pod-root.test.ts against the solid-crud-tests example server. Read the failing Notification and Alice's storage root cases to identify why the advertised links, emitted notifications, and container response differ from expectations. Done means the listed tests pass.
