Removing developer nav

[internetisaiah]

Why are you making this change? (required)

The developer_nav is fairly unintuitive--mostly due to not being a standard feature on other tech-doc sites. Furthermore, this feature will be removed as a part of the #8078. Because of these reasons, we are opting to remove this feature now.
