* ci: unpin the wasi-nn tasks from an older Ubuntu
Previously, OpenVINO's lack of APT packages for Ubuntu 22.04 (`jammy`)
prevented us from upgrading the GitHub runner to use `ubuntu-latest`. I
updated the `install-openvino-action` to substitute in the `focal`
packages in this case (this is what the OpenVINO team considers the fix)
so this pin should no longer be necessary. Fixes#5408.
(Run all CI actions: prtest:full)
* vet: audit the openvino version bump
