ci: Fix Docker publishing for CSI driver, 2nd try

Follow-up to #10609 as it seems GHA doesn't allow hard links:

https://github.com/kata-containers/kata-containers/actions/runs/12144941404/job/33868901896?pr=10563#step:6:8

Note that I also updated the `needs` directive as we don't need the Kata
payload container, just the tarball artifact.

Part of: #10560
