Fix instaslice-operator build_root to use Go 1.23

[harche]

Summary

PR #74222 changed the build_root image from golang-1.22 to rhel-8-release-golang-1.22-openshift-4.18, but instaslice-operator requires Go 1.23 (per go.mod).

The rhel-8 image has GOTOOLCHAIN=local which prevents auto-downloading Go 1.23, causing unit tests to fail with:

go: go.mod requires go >= 1.23.0 (running go 1.22.9; GOTOOLCHAIN=local)

This PR updates to rhel-9-release-golang-1.23-openshift-4.20 which has Go 1.23.
