✨ Allow exporting engine logs

[sagikazarmark]

What are you trying to do?

I'm trying to debug dagger/dagger#7593, but there is no way in the action to export engine logs.

Why is this important to you?

Figure out why Dagger is slow.

How are you currently working around this?

I'm using this snippet:

      - name: Export Dagger Engine logs
        run: docker logs $(docker container list --all --filter 'name=^dagger-engine-*' --format '{{.Names}}') > engine.log
        if: always()

      - name: Upload Dagger Engine logs as artifact
        uses: actions/upload-artifact@c7d193f32edcb7bfad88892161225aeda64e9392 # v4.0.0
        if: always()
        with:
          name: "Dagger Engine logs"
          path: engine.log
          retention-days: 14

But the engine log comes back basically empty, because the action is terminated due to a timeout.
