update: ray to latest version to upgrade commons-lang3

[kirupang-code]

The old version of ray uses a commons-lang3 version associated with a vulnerability. This was fixed in the recent version of ray. .

Also updated pre-commit and autoflake versions to fix linting errors:

Warning:  repo `[https://github.com/pre-commit/pre-commit-hooks`](https://github.com/pre-commit/pre-commit-hooks%60) uses deprecated stage names (commit, push) which will be removed in a future version.  Hint: often `pre-commit autoupdate --repo [https://github.com/pre-commit/pre-commit-hooks`](https://github.com/pre-commit/pre-commit-hooks%60) will fix this.  if it does not -- consider reporting an issue to that repo.
