Deploy pages from archives using archived tools

Rather than iterating over the available branches, checking them out and building the pages, we are going to render the pages in a separate jobs and pick up the artifacts created by those jobs. Tweak the template render-pages in .gitlab-ci/templates-render-pages.yml to retrieve and extract the artifacts rather than generating the pages. Tweak the naming to be more consistent with its new role.

We need the tools to generate the main menu on every branch that generates test-cases. Rather than copying the tools to them all, keep the tools here, archive them and pull out the archive in the template which is also stored on this branch.
