Local ruff check does not match up with remote ruff check

[norswap]

When running the check on #12 (before I fixed it) (transcript):

Successfully installed ruff-0.0.285
libroll.py:55:45: E721 Do not compare types, use `isinstance()`
Found 1 error.
make: *** [Makefile:2: linter] Error 1

Locally I have ruff 0.0.284, which the install.sh script is happy to accept. We should make sure that if the users reruns source scripts/install.sh then the results of ruff matches up to the server (by constraining version in both of these places?).

it seems ruff releasing very often. If we always use latest version, we will get lint issues even no code/minor code change. Probably we need focus a version right now? @norswap @ayazabbas @eerkaijun

Yes, let's just settle on the latest version right now, and we'll update it periodically :)
