Download redirection generate an url containing a double "/"

When we download the latest version of fail2ban_exporter the 302 redirect does contain a double "/" that leads to a 308.
The translation from project name to project ID seems to have an extra “/” that is redirected with a 308 on the url without the double “/”.
It does leads to an issue with CI testing of ansible roles when testings agains version of python that do not manage 308 status code, it's a blocker for the ansible playbook to install the exporter:
