OSAC-360: Update Go version in fulfillment service config

[adriengentil]

Summary by CodeRabbit

This PR updates the Go build environment for the OSAC Project's fulfillment-service CI configuration. Specifically, it updates the build_root image stream tag used by the CI system to build the fulfillment-service component:

• Go version: Updated from 1.25 to 1.26
• OpenShift target version: Updated from 4.21 to 5.0

The change modifies a single configuration file (osac-project-fulfillment-service-main.yaml) that defines the CI pipeline for this service. The build_root image is the base container used by the CI system to compile and build the fulfillment-service, so this update ensures the component is built with the newer Go toolchain and against the updated OpenShift release stream.

The PR references OSAC-360 but lacks a proper target version specification in the corresponding Jira issue, as noted by the OpenShift CI automation.

[openshift-ci-robot]

@adriengentil: This pull request references OSAC-360 which is a valid jira issue.

Warning: The referenced jira issue has an invalid target version for the target branch this PR targets: expected the task to target the "5.0.0" version, but no target version was set.

Microshift Test Compatibility	✅ Passed	PR changes only the build_root.image_stream_tag in a YAML CI configuration file; no new Ginkgo e2e tests are added, making the MicroShift compatibility check not applicable.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	This PR only updates Go version in a YAML configuration file. No new Ginkgo e2e tests (It(), Describe(), Context(), etc.) are added, so the SNO compatibility check is not applicable.
Topology-Aware Scheduling Compatibility	✅ Passed	PR changes only a CI build configuration (Go version in build_root.image_stream_tag), not deployment manifests, operator code, or controllers. No scheduling constraints are introduced.
Ote Binary Stdout Contract	✅ Passed	PR only modifies YAML CI/CD configuration (Go version/tag), not executable code. OTE Stdout Contract check applies to code execution contexts, not configuration metadata.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	PR only modifies CI config (image_stream_tag), not Ginkgo e2e tests. No new tests added; check is not applicable.
