moved from galaxyproject/tools-iuc#4830

in the called workflows in order to make it useable in the
tests running here. where we do not use

```
uses: galaxyproject/planemo-ci-action@v1
```

but

```
uses: ./
```

and add statistics output to test workflow

This reverts commit 56ab325.

impossible, because we can not use `uses: ${{ planemo-ci-action }}`

lets see if `uses: ./` just does the intended

hoping that:

- tests in this repo will use the action of the PR branch
  (the workflow version ./ is used .. so hopefully also the
   action ./ is used)
- external callers will use the workflows with
  `galaxyproject/planemo-ci-action/.github/workflows/...@vX`
  and I hope that this also yields version X of the action

and use in test

linter complains otherwise

linter insists

and revert all the test tool changes
