Link to the infra repo that generates the Galician patterns book

[spier]

The translation of our patterns to Galician ("Modelos InnerSource") was even printed! :)

The sources for generating this book are available here: https://eira.mancomun.gal/mancomun/modelos-innersource

Should we link to this from our repo? (what are the benefits? would anybody use this?)

Or possibly even mirror this into the InnerSourceCommons org to keep it available?
