Support ARM

Shall defer to a member of the team here:

ARM64 Production Level Reliability

While we use ARM for PostgreSQL and Redis production hosting, and we have made the Ruby app ARM64 compatible since Discourse on a Raspberry Pi | Blog, we don’t host production traffic from our hosting in ARM yet. That said, as long as you can safely store database backups off-site and monitor the website for error/response times reliably, it should be safe to give ARM in production traffic.
