Add aliases for designs.apertis.org index page

Add aliases to the main website page for the index page URLs as redirected from designs.apertis.org. We are redirecting to the main page as the contents of designs.apertis.org is in the process of being amalgamated into the website structure and thus not all the designs content will end up under one topic.
