Move the comment section attached to the Kraken in advanced.yml

This is to fix a shortcoming in the autoupdate-config loader, which will attach related comments to nodes.
Issue: A nodes will get comments from another node of the same name, anywhere else in the config.
Solution: Move the comment to be attached to the "Kraken" node.

Long term: This can be a known bug and worked around by the team, or can be addressed more seriously by looking into changing how comments are applied to configs.  For now, this is a patch solution that should work fine.

Fixes #1043
