Needs the download directory prefix

[jaygooby]

Looks like the spigot.yml was missing the download/ prefix (where the latest.yml file lives) as this was failing for me:

ansible-playbook -i spigot.example.com, playbook.yml

[DEPRECATION WARNING]: Included file '/Users/jay/ansible-minecraft/latest.yml' not found, however since this include is not explicitly marked as 'static: yes', we will try and include it
dynamically later. In the future, this will be an error unless 'static: no' is used on the include task. If you do not want missing includes to be considered dynamic, use 'static: yes' on the include or
set the global ansible.cfg options to make all includes static for tasks and/or handlers. This feature will be removed in version 2.7. Deprecation warnings can be disabled by setting
deprecation_warnings=False in ansible.cfg.

The attached PR means that spigot now builds and runs
