[FIX] web_kanban_gauge: set auto install True

case: web_kanban_gauge has been added in the dependance of sale_crm. This module used to auto install when module sale and crm were installed. With this new dependance, the module sale_crm auto install when sale, crm and web_kanban_gauge are installed. We auto install kanban gauge so sale_crm auto install on installation of crm and sales, as web_kanban_gauge will be already installed
