Better documentation around interchangeability of GC features

[jeffkala]

Environment

• Python version: all
• Nautobot version: 1.5.x
• nautobot-golden-config version: next

Came up in some internal conversations with @lampwins

Proposed Functionality

Update documentation to explain a better story around the GC features (backups, intended, compliance) and the ability to use the features or to ignore/not use the features.

Use Case

Ensure users understand this application has multiple features and they're all interchangeable.
