fix: make hugo render all pages

[rvagg]

Hugo update seems to have messed up rendering subpages. https://multiformats.io/multiaddr and https://multiformats.io/multihash are missing.

_index.md seems to be special now? with just index.md only index.html is rendered, but with _index.md both the sub-pages are rendered but the index isn't. Adding in layouts/index.html seems to make the index render from _index.md.

Same problem fixed in #78, but in a little different way.
