role not compatible with ansible 2.7 since snap

[wschoot]

It seems that the addition of snap breaks things for Debian 10's default Ansible (2.7.7) which has no support for snap (added to Ansible in 2.8 according to https://docs.ansible.com/ansible/2.8/modules/snap_module.html#snap-module). This may break other older Ansible installations as well and this should be reflected in the minimal ansible version (which is now set to 2.4 on galaxy).

wouter@tosca:~/git/tosca[master]$ ansible-playbook main.yml 
ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.

The error appears to have been in '/home/wouter/.ansible/roles/geerlingguy.certbot/tasks/install-with-snap.yml': line 25, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

- name: Install certbot via snap.

Ansible 2.7 is no longer supported; I would recommend installing Ansible via pip to get a newer version.

Hi Jeff,

Thanks for your insightfull remark, I'm gonna update Ansible. I do however feel it's fair to point out, as a closing note, that the minimum ansible version (2.4) for this module should be raised on the galaxy page. Thanks for all your work!
