Guide mistake?: run tests don't support extra-packages

The readme example has this
```
      # run unit tests with coverage upload
      - uses: SublimeText/UnitTesting/actions/run-tests@v1
        with:
          coverage: true
          extra-packages: |
            A File Icon:SublimeText/AFileIcon
      - uses: codecov/codecov-action@v4
```
That seems to only be a setup-action field? Got a warning trying to use as written in the run-test action
