composed-tox-sonar-cloud.yaml is broken

[zxiiro]

It seems the workflow composed-tox-sonar-cloud.yaml is broken and throws the following error:

Error
reusable workflows should be referenced at the top-level `jobs.*.uses' key, not within steps

Looks like there is a misconfiguration in the yaml somewhere.

You're right, it's because the tox-verify workflow is being called from a step, whereas re-usable workflows have to be called as self-contained/top-level jobs. I suspect the subsequent step:

- name: Run Sonar Cloud scan
  uses: sonarsource/sonarcloud-github-action@master

...needs to be merged into a single core workflow, where the two steps can be called together? We'll need to check where it is being used though, as changing the behaviour might cause unintended breakage. However, I suspect the tox-verify step might instead be better constructed as an action, which would also solve the problem?
