lamp-infrastructure: missing firewall referrenced in main.yml

[EdZilla]

https://github.com/geerlingguy/ansible-for-devops/blob/master/lamp-infrastructure/playbooks/varnish/main.yml
Error is:
The error appears to have been in '...ansible-for-devops/lamp-infrastructure/playbooks/varnish/main.yml': line 9, column 7, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

roles:
- geerlingguy.firewall
^ here

I missed it here too:
Run ansible-galaxy install -r requirements.yml to install require Ansible roles.
embarrassed.

@EdZilla - It happens to the best of us! No problem at all.
