* Guide: Reindent the router module with 4 spaces

The guide used to use 2 spaces for indentation. The problem with that is `mdbook` doesn't recognize them as a proper indentation and thus doesn't render indent properly.

A couple of things are not indented here because they will be changed in the following commits

* Guide: a bunch of fixes

* Add reward limits

* Fix weight tests and whatnot

* add weight files

* Update runtime/kusama/src/lib.rs

* "Update Substrate"
