Move the section Get Started to the top of the Nav bar

[liviolanda]

As a user, I want to see first what I need to Get Started with Storj DCS before learning about concepts and company.

While we don't update the full documentation, I moved the section to the top of the navbar in gitbook, so it's more visible to users. I need this change to be merged.

@liviolanda Please post the link to the gitbook draft that needs to be merged

This change is controversial to suggestion to move Downloads up.

@AlexeyALeonov and @heunland I'm gonna close this ticket because we're addressing all these problems together in the new UX, which will be implemented soon. thanks!
