57a5285020 ci: turn off cosign's signing config alongside the bundle format (#11144)
Every image-signing job has failed since signing was added (#11129):

  must provide --new-bundle-format or --bundle where applicable with
  --signing-config or --use-signing-config

Cosign 3 turned on two defaults, not one. The action only disabled
--new-bundle-format to keep the .sig tag layout, but --use-signing-config
is still on, and cosign refuses that pairing because the signing-config
path has nowhere to write its verification material without a bundle.
Disabling it too falls back to the default Fulcio and Rekor URLs, the
same services the .sig layout always used. The verify step needs no
change: cosign verify looks for a referrer bundle first and falls back
to the .sig tag when there is none.

Keyless cosign signature on each image, then a verification pass against the

The calling job needs `id-token: write` and a registry login for every image.
