Update dependency kubernetes/kubernetes to v1.35.9

github.repository_owner is populated on this Gitea instance: measured as
"jlab-cluster" (12 characters) in run 282 of validate-charts.yml. The
value is now in the comment above the upload step, so the fact survives
without the step that produced it.

Both halves of that composition are guarded, because the only other signal would be a 404 against a URL the log has masked: `charts-url` is rejected unless it ends in `/api/packages` (an old, full URL still carrying `/helm`, `/api/charts` or the owner is named explicitly in the error), and the derived owner is rejected when empty or when it is not a usable path segment — an empty one would build `<base>//helm/api/charts`.

Each value is additionally guarded with `:?`, because an empty one used to collapse into a missing argument rather than an error. Three properties of the upload step are load-bearing:
   - **Credentials stay out of the process list.** `curl --user "$U:$P"` would put them in `argv`; the step uses `curl --config -` and pipes the options in on stdin instead.
   - **A failed upload fails the job.** Unlike `helm push`, `curl` exits **0** on HTTP 401/403/409 — a publish would go green with nothing uploaded. `--fail-with-body` turns those into a non-zero exit and still prints the response body, so the log names the cause.
   - **The file name is built, not globbed.** `<chart>-<version>.tgz` is assembled from the chart name and the version already read from `Chart.yaml`; `--upload-file` takes exactly one file, and a glob matching two silently turns the second into curl's URL argument. `helm package` keeps the `+` of a `1.4.0+up1.9.2` version verbatim in the file name, so the built name is an exact match.
