MGMT-24455: update IBIO CI build root to Go 1.26

[shay23bra]

Summary

• Update IBIO CI build root from rhel-9-release-golang-1.25-openshift-4.23 to rhel-9-release-golang-1.26-openshift-5.0 (main + backplane-5.0)
• Required for the Go 1.26 upgrade in MGMT-24455: upgrade to golang 1.26 image-based-install-operator#843

https://redhat.atlassian.net/browse/MGMT-24455

Summary by CodeRabbit

This PR updates the CI build root configuration for the Image-Based Install Operator (IBIO) to use Go 1.26. Specifically, it modifies the CI pipeline configurations for both the main and backplane-5.0 branches to use a newer RHEL 9 base image with Go 1.26 instead of the previous 1.25 version.

Changes:

• Updated ci-operator/config/openshift/image-based-install-operator/openshift-image-based-install-operator-main.yaml to reference rhel-9-release-golang-1.26-openshift-5.0
• Updated ci-operator/config/openshift/image-based-install-operator/openshift-image-based-install-operator-backplane-5.0.yaml to reference the same Go 1.26 image

This aligns the IBIO's CI infrastructure with the Go 1.26 upgrade effort and ensures both branches build with the newer Go version and OpenShift 5.0 base image.

Walkthrough

This PR updates the Go toolchain and OpenShift version used for building the image-based-install-operator. The build root image stream tag is bumped from rhel-9-release-golang-1.25-openshift-4.23 to rhel-9-release-golang-1.26-openshift-5.0 in both the backplane-5.0 and main configuration files.

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title clearly and specifically describes the main change: updating the IBIO CI build root to Go 1.26, which matches the two YAML configuration file updates.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names	✅ Passed	PR contains only CI configuration file changes updating Go version tags; no Ginkgo test files or test title declarations are present, so the test naming check does not apply.
Test Structure And Quality	✅ Passed	PR contains only CI/CD pipeline configuration YAML files, not Ginkgo test code. The custom check for test structure and quality is not applicable to this pull request.
Microshift Test Compatibility	✅ Passed	No new Ginkgo e2e tests are added in this PR; it only updates CI configuration files with Go version changes, so the MicroShift test compatibility check is not applicable.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	This PR only updates CI build configuration YAML files with a Go version upgrade (1.25→1.26) and adds no Ginkgo e2e tests, making the SNO compatibility check inapplicable.
Topology-Aware Scheduling Compatibility	✅ Passed	This PR only updates CI build configuration (Go version in build_root), not deployment manifests, operator code, or controllers; therefore the topology-aware scheduling check does not apply.
Ote Binary Stdout Contract	✅ Passed	PR only modifies CI configuration files (.yaml/.OWNERS); no application code changes; OTE Binary Stdout Contract check not applicable.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	PR contains only CI configuration changes (Go version update), not new Ginkgo e2e tests. Check requires new tests to be added; condition not met.
No-Weak-Crypto	✅ Passed	PR contains only CI configuration updates (Go version tags), no cryptographic code changes or weak crypto patterns introduced.
Container-Privileges	✅ Passed	PR updates only CI operator pipeline configs with Go version upgrade. No container privilege escalation flags found in the code changes.
No-Sensitive-Data-In-Logs	✅ Passed	PR only updates Go version tag (1.25→1.26) in CI config files; no logging statements or sensitive data (passwords, tokens, API keys, PII) added or exposed.
