There was a change the environment variables in spindle that were not reflected in this nix module, specifically STEP_TIMEOUT was renamed to WORKFLOW_TIMEOUT, which means that there was no way to set the timeout in the nix module. With the option name being updated, this is a breaking change that will require you to update your nix config if you are using the spindle module. Signed-off-by: Samuel Shuert <me@thecoded.prof>
