Update main.tf

Added a terraform and provider block - terraform relies on plugins and following best practices to allow allowing the rightmost component of a version to increment. (https://developer.hashicorp.com/terraform/language/providers/requirements#version-constraints)

Also removed comment about it being ok to use project roles of monitoring viewer and compute networkViewer. (Look at Issue #922)
