playbook: sshd service is ssh for ubuntu 24
Distributions have different names for openssh-server systemd service:
- In Ubuntu < 24 and Debian: ssh and sshd are valid
- In Ubuntu 24: only ssh is valid
- In Fedora: only sshd is valid
This commits uses sshd if distribution is Fedora, else ssh
I couldn't find any better way to do this than having two handlers, let me know if someone has a better idea.
