Add search_keywords to Community model

Add a ArrayField to the Community model to enable slitghtly more
optimized search. The field stores an array of strings and matches the
search query to these keywords, alongside filtering by community name.

This allows users to find communities with short abbreviations or
alternative stylings of community names.

Add the search_keywords field to CommunityListAPIView search_fields.

Implement tests with various test cases for CommunityListAPIView
endpoint.
