Add `fedora:41-ci` CI image with `sudo` user

[abitrolly]

For CI systems it is beneficial to have an image that comes with default user other than root. The user should have sudo enabled though, for easy package installation.

Right now the user needs to be created manually.

adduser fedora -G wheel

sudo under this user still asks for a password. This won't work for CI.

EDIT: Disable sudo password for fedora user.

echo "fedora       ALL=(ALL)       NOPASSWD: ALL" > /etc/sudoers.d/fedora

This still doesn't work well for CI, because now every user command needs to be run as sudo -u fedora <command>.

@jsf9k I don't think --privileged is related here. It is all internal details of podman or docker.
