HYPERFLEET-1311: bump hyperfleet-sentinel CI builder to Go 1.26

[kuudori]

Bumps build_root.image_stream_tag for hyperfleet-sentinel from rhel-9-golang-1.25-openshift-4.21 to rhel-9-golang-1.26-openshift-4.23 in both the main and presubmits ci-operator configs.

Companion to #81343 (HYPERFLEET-1309, adapter) and #81494 (HYPERFLEET-1310, api), same tag change. Aligns Go version across HyperFleet components: https://redhat.atlassian.net/browse/HYPERFLEET-1311

Summary by CodeRabbit

Updated the HyperFleet Sentinel CI configuration to build against Go 1.26 instead of Go 1.25, aligning its main and presubmit jobs with the newer OpenShift 4.23-based builder image. This keeps the Sentinel CI setup in step with the related HyperFleet component updates and ensures the pipeline uses the same Go toolchain version across the suite.
