Add GitHub Actions badge and remove sr.ht

My first time setting up a PostgreSQL service container on GitHub
actions. Note that there are two different kinds of environment
variables: those passed to the Docker container, and those used by
the PostgreSQL utilities.

See: https://docs.github.com/en/actions/guides/creating-postgresql-service-containers

 DSpace stores item view and download events in a Solr "statistics" core. This information is available for use in the various DSpace user interfaces, but is not exposed externally via any APIs. The DSpace 4/5/6 [REST API](https://wiki.lyrasis.org/display/DSDOC5x/REST+API), for example, only exposes _metadata_ about communities, collections, items, and bitstreams.
 
 - If your DSpace is version 4 or 5, use [dspace-statistics-api v1.1.1](https://github.com/ilri/dspace-statistics-api/releases/tag/v1.1.1)
