Description (What does it do?)

This PR:

• removes useSearchQueryParams, which has not been used in any production code
• adds useResourceSearchParams, useContentFileSearchParams. These hooks:
  • calculate parameters for MIT Open's /api/v1/learning_resource_search or /api/v1/content_file_search based on a URLSearchParams object.
  • provide setters to assist in setting the search params.
  • See https://github.com/mitodl/course-search-utils/pull/78/files#r1538448263 for more
• Exports AvailableFacets, a portion of the existing FacetDisplay component.
• Replaces the in-repo generated client with client from https://github.com/mitodl/open-api-clients
