[ospdo] Pass GOLANG_BASE for Go 1.26 CI build root image

[stuggi]

The ci-build-root-golang-1.26-sdk-1.42.3 image was being built without overriding GOLANG_BASE, so it defaulted to Go 1.24 from the Dockerfile. Pass the Go 1.26 base image explicitly.

Jira: OSPRH-32127

Summary by CodeRabbit

Updated the OpenStack K8s Operators CI build-root image configuration so the Go 1.26 SDK image is explicitly used as the base. This fixes the ci-build-root-golang-1.26-sdk-1.42.3 image build for the openstack-k8s-operators CI setup, preventing it from falling back to the older Go 1.24 default and aligning the CI image with the intended Go 1.26 toolchain.
