Drive installation doesn't mention required template

The Drive addon installation documentation does not mention about the "drive" template that is required by the Drive deployment.

Normally, the Drive addon would automatically deploy the "drive" template, but this is not the case with some docker-based deployments that override the nuxeo.templates parameter in the nuxeo.conf.  In those cases, the full list of templates must be listed as detailed in NXP-29920.
