the Layouts Are Squib’s Best Feature documention has some broken links

[joem]

The links to the built in layouts are broken. In the docs, the layouts are at:

https://github.com/andymeneely/squib/tree/master/lib/squib/layouts/

But those links don't work and in the current version of the repo they're actually at:

https://github.com/andymeneely/squib/tree/master/lib/squib/builtin/layouts/

So, for example, the link to the hand layout currently reads https://github.com/andymeneely/squib/tree/master/lib/squib/layouts/hand.yml but it should actually read https://github.com/andymeneely/squib/tree/master/lib/squib/builtin/layouts/hand.yml.
