Add a Github action to deploy

This replaces Travis as the integration tool with Github Actions. The
benefit is that it can also deploy to the gh-pages branch. This can then
be deployed automatically after merge.

It also switches from Gitbook legacy to Honkit. Since Github legacy is
being phased out, this is needed.
