Changes

Bump the pinned ko and koparse image digests in
tekton/build-publish-images-manifests.yaml to versions built with
Go 1.26.5.

Root cause

go.mod was updated to require go >= 1.26.5, but the previously
pinned images baked in Go 1.26.4. Because the release pipeline runs
with GOTOOLCHAIN=local, ko resolve failed with:

go: go.mod requires go >= 1.26.5 (running go 1.26.4; GOTOOLCHAIN=local)

Fix

Update both digests to the latest ghcr.io/tektoncd/plumbing images
(sha-a4f94ba, published 2026-08-10) built from
golang:1.26.5-alpine:

Image Old digest New digest
ko 7561ceb… 976eb63…
koparse 6cf5d09… e060328…

Cherry-pick targets

This fix needs to be cherry-picked to:

  • release-v0.81.x (blocking v0.81.0 patch release)
  • release-v0.80.x (prevent future patch release failures)

/kind bug

Fix patch release pipeline failures caused by Go 1.26.5 requirement
mismatch in pinned ko/koparse images.

The pinned ko/koparse images baked in Go 1.26.4, but go.mod now
requires go >= 1.26.5, causing ko resolve to fail with
GOTOOLCHAIN=local on patch releases.

Bump both image digests to the latest plumbing images built from
golang:1.26.5-alpine (ko sha-a4f94ba, published 2026-08-10):
- ko:      sha256:976eb63...ffbeec3
