missing task parameter added, unified commands (#3672)

* missing task parameter added, unify command running

* adding hf token env to enable model pulling

* updated hftoken at the correct place

* Removing HF_TOKEN, because tests now handle this case

* adding hf cache to the docker files

* adding labels for advancement level

* corrected parameter position

* Changed requirements link to enable windows tests

* changed env variable to be consistant with windows

* changed path to fit windows convention, added linux alternative
