Remove jQuery AJAX from the notifications (#29817)

- Removed 2 jQuery AJAX calls and replaced with our fetch wrapper
- Deleted an AJAX call that wasn't attached to any element since #24989
- Tested the notification count and notification table functionality and
it works as before

# Demo using `fetch` instead of jQuery AJAX
