Fix build when http_prefix is configured

This allows us to build the site with absolute URLs (rather than relative) and have features like search working without post-build edits. This moves us closer to an automated build. Builds need to consider the http-prefix because Github pages for repo-specific sites include the repo name in the first segement of the path, e.g: https://alphagov.github.io/api-catalogue/ The fork of tech-docs-gem is intended to be temporary, until fixes for issues documented here have been resolved & merged upstream: #95
