Embedded snowflake client URL redirect is giving a 404

In light of #14 (closed), the URL redirect from snowflake.torproject.org/embed is giving a "404 Not found" error. We have this URL listed in the Support Entry about running Snowflake proxies, https://support.torproject.org/censorship/how-to-help-running-snowflake/ (separate ticket for updating the support entry: support#385 (closed))

snowflake.torproject.org/embed.html is redirecting to https://embed-snowflake.torproject.org/ just fine.
