Switch the Mediawiki config to the new LDAP dir structure

* Use a new read-only account instead of the admin LDAP account
* Disable the LDAPAuthorization plugin. The LDAPAuthentication2 plugin
is still used to authenticate users, but every kosmos.org user has
access to the wiki. See
https://www.mediawiki.org/wiki/Extension:PluggableAuth for the
distinction between authentication and authorization
