Rename directories in multi-gpu regression tests

When running the regression tests on 4 and 8 GPUs at the same time, one of them fails due to missing files.

I think the cause is the clean stage in the rocketGPU.yml file.

clean:
  - multigpu_test/*

Since the directory had the same name for both tests, one test may have deleted the data of the other test. Therefore, I renamed the directories.
