fix typo: reload slurmdbd->Reload slurmdbd

[Oberfeldwedler]

I think this is a Typo. The handler reload slurmdbd doesn't exist.

from handlers/main.yml

- name: Reload slurmdbd
  ansible.builtin.service:
    name: "{{ slurmdbd_service_name }}"
    state: reloaded
  when: "slurm_start_services and ('slurmdbdservers' in group_names or 'dbd' in slurm_roles)"

Looks good to me. 👍
