This will fix the problem where embeds on Mastodon posts, the "show original" link in many clients, and clicking on the username on the user profile on Mastodon were redirecting to a raw JSON page in your browser. We still respond with JSON when it's requested in various forms (I left it open-ended since other Postmarks instances aren't correctly requesting the LD version of JSON yet).
