Rename test_distributed to test_distributed_fork (pytorch#42932)

Summary:
Pull Request resolved: pytorch#42932

Follow up from pytorch#41769, rename `test_distributed` to `test_distributed_fork` to make it explicit that it forks.

New command to run test:
`python test/run_test.py -i distributed/test_distributed_fork -v`
ghstack-source-id: 111632568

Test Plan: `python test/run_test.py -i distributed/test_distributed_fork -v`
