use $HOME/.volt/config instead of $HOME/.volt/config-minimal

* we are currently only using and generating $HOME/.volt/config during
  our pipeline runs, and should not use any arbitrary configuration file
  like $HOME/.volt/config-minimal where we do not know the content nor
  its origin
* replace the usage of $HOME/.volt/config-minimal with
  $HOME/.volt/config for all jobs
