publish-tauri action broken CI, can't find private key

After creating the bundles, the signing fails in the CI:

https://github.com/atomicdata-dev/atomic-data-rust/actions/runs/2984072526/jobs/4784311358#step:7:831

     Finished 3 bundles at:

        /Users/runner/work/atomic-data-rust/atomic-data-rust/target/release/bundle/macos/Atomic Server.app.tar.gz (updater)

       Error A public key has been found, but no private key. Make sure to set `TAURI_PRIVATE_KEY` environment variable.
Error: Command failed with exit code 1: tauri build

TAURI_PRIVATE_KEY is in fact a configured secret, so I don't know why it's complaining. Maybe setting it as a Repository secret isn't enough?

Apparently I fixed this 11 days ago. We'll see if it works when I push a new version.
