Test Build Version changes

[ldbiz]

The w3act build process has been integrated into the new workflow (ukwa/ukwa-services#77)

Although its been tested for the underlying proof of build and security scanning, I forgot to test the version changes actually work beyond not tripping up the build. As this isn't a security issue, I've created a separate task here to track it.

ie. the build should include a version tag when specified, and default as the other repos when not specified.
