[DOCS] Add list of inventories with descriptions (#498)

Previously I could look into the settings.cfg to see keys and names of
interlink inventories (because I do not know them all by heart), but now
this is only available in the render-guides repository.

There seems to be a twig directive to get the enum values and their
links, but I acutally need more:

* The name of the inventory as rendered for the Title
* The actual URL used
* The key of the inventory

So I made a manual list of this because I didn't want to enhance the
ENUM to do too many things.

At least I need such a list, up to you if we want to maintain this in
the docs this way, or if we would need a dynamic way...?!
