Delete worker results on selection

Depends https://gitlab.com/arkindex/backend/-/issues/929

Refs https://gitlab.com/arkindex/requests/-/issues/547

Once the use_selection option is available, we need to expose the new feature on the frontend:

1. add a new option named "delete worker results"
2. once selected, a modal appear, listing all worker versions, allowing to select one or none
3. then the call is made and a new async task is created
