These five doc changes correct doc bugs and format errors that have caused users pain. I propose that we back-port them to support/1.13:
GEODE-8193: Broken link in statistics list GEODE-7956, GEODE-7519: Docs should mention dot as a valid region name character GEODE-8304: Better highlight steps for building documentation GEODE-8237: Add note about 'alter region' and cluster conf service in doc
