Add mage-cugraph Docker image to the documentation

[kgolubic]

There is a mage-cugraph Docker image but we don't mention it in our documentation. We should add it. This image is referenced in https://developer.nvidia.com/blog/running-large-scale-graph-analytics-with-memgraph-and-nvidia-cugraph-algorithms/.

I have trouble identifying where to place information about this image...

So anywhere we mention any images (like instructions and how-tos when different images have different steps), that's easy.

But we don't have 1 location that lists all the images... So my suggestion is maybe to create a table at the end of the page below with info about what images we have, and what they include:
https://memgraph.com/docs/memgraph/installation

Also, how are all the other images installed? Like MemgraphDB? Could we maybe improve the Install Memgraph DB by adding examples for all three images that install MemgraphDB + something that is not the full package?

I agree with your suggestion of adding a table at the bottom of the page. We should just then link MAGE documentation (https://memgraph.com/docs/mage/installation/cugraph) when we mention mage-cugraph.
