DEV: add CC-0 public domain dedication to governance document

We want to allow other projects to steal from us, like we stole from
Jupyter/IPython :-). This relicensing / public domain dedication is
possible because all text here is either by me (and thus copyright me)
or else taken from the Jupyter/IPython document, and their document is
also under CC-0 as per https://github.com/jupyter/governance/pull/9
