website/docs: added a new template for "combo" topics

[tanberry]

Added a new template for combo topics, which works for the vast majority of our docs. It's a combination of conceptual and procedural information. Only really massive features need to have conceptual and procedual info split into two documents.

• The documentation has been updated
• The documentation has been formatted (make website)
