Inconsistency between openprinting.org and openprinting.github.io

[tbertels]

The websites link to each other instead of keeping the user on https://openprinting.org

The reason seems to be that https://www.openprinting.org redirects to https://openprinting.github.io

I suggest redirecting everything to https://www.openprinting.org

@rudra-iitm any chance to get this to work? Having everything here on GitHub but the URLs are not https://openprinting.github.io/... but https://www.openprinting.org/...?
