[Theme Handbook Overhaul] Publish Chapter: Patterns

[justintadlock]

Now that the Patterns chapter is fully drafted, it is time to begin moving this new chapter to the Theme Handbook.

This is a sub-tracking issue for #816. I've created this ticket so that it's easier to manage and coordinate the process for this new chapter that is being added. We can also use this to add any notes for things we need to know as we move through the larger Theme Handbook Overhaul project.
