Documentation links broken, indexed by Google

Internal documentation links like https://cassandra.apache.org/doc/latest/operating/compaction/index.html are now returning 404s. These links originate from within documentation (referenced from https://cassandra.apache.org/doc/latest/) and are indexed by Google (first result for "apache cassandra compaction", for example).

These links were working correctly as recently as late 2020: https://web.archive.org/web/20201020194414/https://cassandra.apache.org/doc/latest/operating/compaction/index.html
