fixing formatting in container image to be consistent with image (#206)

Issue #, if available:
N/A

Description of changes:
This PR aims to keep how `containerImage` tag is generated/built consistent and insync with how `image` tag in the cluster service version is generated. This makes readability of both sections of code/templates/sh's/etc the same and easier in the future if a change in the formate is needed.
