Update suggested commands for the new addWiki.php
- You can push the new configuration out everywhere, with the new DB in preinstall.dblist, rather than pulling into a maintenance host. It's probably slower but it will work with k8s.
- No need for dummy wiki or configuration details on the command line
- No need to run UpdateSearchIndexConfig after Ic6b2bda46b548a271ef5811
- Fix typo
