docs: Spread out doc order numbers

So we don't have to change them all whenever we add a new page.

This reserves 10 numbers for each "type" of plugin documentation:

 - 0-9 · introduction (getting started etc)
 - 10-19 · plugin meta (only the list right now)
 - 20-29 · UI plugins
 - 30-39 · Uploaders
 - 40-∞ · Other

Read more about it [on the blog](https://uppy.io/blog/2017/07/golden-retriever/).
