redirect_from plugin doesn't seem to be working

What's wrong? Describe the what you're seeing

We've had the "redirect_to" plugin installed, to let us create temporary redirects for when we don't have immediate access to NGINX. This plugin is supposed to create a stub page at the redirecting address with a built-in meta redirect tag. For some reason this is no longer working.

Problem location

Check this out in #510 where I'm trying to prevent a renamed integration (impact radius -> impact) from 404ing once I've corrected the slug.

Suggestions for a fix

Looking at the generated local jekyll site it looks like it's not actually creating the stub page - I'd expect there to be a new folder for /connections/destinations/catalog/impact-radius/ with the stub file and redirect in it. But no such file is generated.

https://segment.com/docs/connections/destinations/catalog/criteo/ should also redirect to https://segment.com/docs/connections/destinations/catalog/criteo-app-web-events/
