Fix build.hcl / CI.yml regarding labels

The version label and versions passed to docs image were based on
the tag. Now we first build the images with -build appended to the
tag, we cannot use the tag as version label.

A new env var is introduced to pass the version to the build.hcl file.
This will be used to set the VERSION label in the image, and pass
as build arguments to the docs image.
