/.well-known/change-password doesn't work

[hangy]

What

• The feature https://web.dev/change-password-url/ doesn't work any more.

Steps to reproduce the behavior

1. Go to https://world.openfoodfacts.org/.well-known/change-password
2. See 404 Not Found page from nginx

Expected behavior

• The user should be redirected to /cgi/change_password.pl.

Additional context

The feature was originally implemented in #4149, and is probably broken since #5685, because .well-known was added to directories to be used for static files, probably for assetlinks.json.

A possible fix is to add the redirect to nginx.com instead of

openfoodfacts-server/lib/ProductOpener/Routing.pm
