LGTM, @roberthbailey you happy?

https://eb37002-dot-preview-dot-agones-images.appspot.com/site/docs/advanced/allocator-service/ is where I'd added the wrapped warnings that weren't rendering. And it looks like I missed a closing tag somewhere, since the bottom warning now spans the whole rest of the page....

[roberthbailey]

I pushed a couple of minor fixes and it's now rendering properly for me locally.
