Seeding tutorial is misleading

[multimedial]

Describe the Bug
The seeding tutorial described in the documentation is misleading:
https://hyperledger.github.io/burrow/#/tutorials/6-seeding

The toml file to be created for the seeding node is to be derived from the toml file from the validators which is being created further below.

To Reproduce
Try to following along the tutorial.

Expected Behavior
The part about the changes to apply to the seeder's toml file needs to be pushed underneath the creation of the burrow_init.toml file, otherwise one might understand the changes to apply to represent the structure of the whole toml file for the seeder's node.

Technical Details
See URL above

Additional Context
I filed another bug for seeding not working when not doing the tutorial on a single machien using the loopback address (127.0.0.1) but on different separate machines. I can't get it to work.
