use a separate workflow for publishing

[proppy]

Currently the CI rely on a current job that "count" the number of completed siblings jobs in order to trigger the publication step to the main litex-hub package: https://github.com/hdl/conda-eda/blob/master/.github/workflows/build-packages.yml#L801

Instead we could consider using something like:
https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#workflow_run to trigger a separate publish-packages workflow once all the build jobs of the build-packages workflow have completed

Note that the default token cannot trigger other workflows (in order to prevent unexperienced users creating infinite loops). You need to use a Personal Access Token in order to be able to trigger other workflows through dispatch. Alternatively, you could use a reusable workflow.
