A couple mypy/ruff fixes (#13001)

* A couple mypy issues

Option `warn_unused_configs` requires turning off incremental mode:
https://mypy.readthedocs.io/en/stable/config_file.html#confval-warn_unused_configs

* The current directory is the default ruff target

No need to specify it explicitly, the same way we don't specifiy it with
mypy or sidst-check.

* Use a decently recent version of ruff

* Partially revert "A couple mypy issues"

This partially reverts commit 34de867.
