Updating Ansible compatibility for Davinci installation

[vic-bart]

Description

I followed the instructions to install Davinci Resolve using Ansible 2.19.5, which caused several errors (see #52). I have found, committed, and pushed fixes to these errors on this fork.
However, note that while I was able to successfully install Davinci Resolve, I have not been able to run it as my Nvidia GPU appears to be incompatible and it is unclear whether the installation script should have resolved this.
(would be nice if someone who knows their GPU works with Davinci on Linux could test these changes).
