Pagination does not work for Courses block/shortcode on a single Course page

[brianhogg]

Reproduction Steps

1. Add a Courses block to a Course page
2. Change limit to 3 instead of -1 on a site with more than 3 courses
3. Save and load the page
4. Try to navigate to page 2

Expected Behavior

Loads page 2 of the courses

Actual Behavior

Reloads the page, /page/2 is not in the URL as it would be on a Page

A workaround if we just want to show 3 courses and no pagination is a bit of CSS:

.single-course .wp-block-llms-courses .llms-pagination {
   display: none;
}

I think we may want to rethink how the pagination works, ie. using AJAX to load it, and having an option to hide the pagination if someone just wants to show 3 courses. Multiple shortcodes on the same page would get confused with each other, for example, but maybe there's a quicker fix to allow the /page/2 to work for courses as well.
