ci: make publish workflow functional by not calling tests.yaml workflow

It would be possible to fix this by adding workflow_call on the tests
workflow I think, but I also know there have been some security concerns
with having workflow triggers, so for now I'll remove this requirement
instead.

> error parsing called workflow ".github/workflows/publish.yaml" ->
  "./.github/workflows/tests.yaml" (source tag with sha:...) :
  workflow is not reusable as it is missing a `on.workflow_call` trigger
