SEO(portal loop): setup redirects from test3.gno.land to gno.land

[moul]

We have launched Portal Loop on gno.land. The new blog home is now Portal Loop.

To avoid significant SEO errors on Google, we should set up an HTTP redirect loop on test3.gno.land for URLs matching r/gnoland/blog/*.

This can be achieved by updating gnoweb in the test3 branch or by enhancing the docker-compose file in the test3 branch with a custom Nginx proxy configuration.

Assigning @gnolang/devrels. I recommend coordinating with @albttx (@gnolang/devops) for the optimal solution.

FYI: I tried last time asked by @leohhhn to setup the latest version of gnoweb on test3, but it's not working as it is.

It would require more than just "updating" gnoweb docker image

@albttx what's the status on this?
