That specific workflow is outdated. It is now possible to set up github as a "trusted publisher" so no personal tokens are required anymore.

Is this a duplicate of #372?

[egpbos]

@bouweandela yes! I knew I had seen it before, but somehow overlooked the very top issue :D Thanks, closing.

Hm, actually no it's not really a duplicate, I'm talking here about actually adding a GitHub Actions workflow to the template.
