ci: refresh check state (re-post required checks on a clean head)

No file changes. The prior head accumulated many check-suites across repeated
force-push rebases, and GitHub's mergeability rollup stopped surfacing the
required 'Kernel E2E' context even though a valid github-actions success
check-run existed on the commit — leaving the PR unable to enter the merge queue
('Kernel E2E — Expected — Waiting for status to be reported'). Pushing a fresh
non-force commit gives a clean check-suite set so skip-kernel-e2e-pr re-posts
Kernel E2E into the current suite and the rollup picks it up.
