Timestamps for noscript users

We currently render relative timestamps via the timeago plugin. Users without javascript enabled don't see them, for obvious reasons.

Solutions

1. Show the ISO date in template, and then swap it out with the relative date, but there would be a flash where the fallback would be visible. Possible to mitigate this via noscript specific scss (we had that at one point, not sure if still around/working)
2. The timeago span is empty and takes up no space already, maybe just add a <noscript> tag next to it.
   • We would need to replace all timeago spans with a helper, though.
