HSEARCH-1644

Docs updates ! :-)
 - https://hibernate.atlassian.net/browse/HSEARCH-1644

I find this a bit confusing.  I would just write:

> Hibernate Search is included in the popular application server, so you don't need to package it
> but remember you need to activate the module, see <<search-configuration-deploy-on-wildfly>> for details.
> Due to he modular design of WildFly, you can also bundle a more more recent Search version than the one included in the app server with your application. This is explained in <<search-configuration-deploy-on-wildfly>>.
