Update all Habitat references to use Helix Examples

[nickwesselman]

With the new Basic Company Helix Examples going public, any Habitat references in existing docs which can be replaced with Basic Company should be removed and replaced.

Below is a quick audit of Habitat mentions. Not all can be replaced immediately due to the limited scope of Basic Company.

• Layers section (2.1.2)
  • Foundation subsection (2,1,2,3) - Basic isn't deep enough in the Foundation layer
• Modules section (2.1.3)
• Domain language section (2.1.4) - Maybe needs to wait for a larger example?
• Implementation structure (2.2.1) - Maybe needs to wait for a larger example?
• Solution structure (2.2.2)
• Projects (2.2.3)
• Module structure (2.3.2)
• Item types (2.4.1)

• Template Structure (2.5.1)
• Template Types (2.5.3) - Can't replace all, maybe should wait?
