Fix ruff version to 0.3.4 in order to overcome issue with version 0.3.5.

[BenZickel]

• Linting with ruff version 0.3.5 fails as can be seen here.
• The failure is due to ruff version 0.3.5 not respecting this directive.
• The problem does not occur with ruff version 0.3.4.

Thanks @BenZickel! Do you have any idea how to get ruff>=0.3.5 to respect __all__?

Hi @fritzo! I think the issue is that ruff 0.3.5 is not respecting the # noqa: F822 directive for all lines of a multiline expression, while ruff 0.3.4 does. I will open an issue in the ruff repo and based on the feedback I get we can decide how to fix this.
This pull request is just a hotfix in the meantime.
