Pin the linter that gates publication

The job header asked for ruff>=0.11,<1, which is whatever ruff released this morning. A new minor added RUF100, four previously clean noqa directives became errors, and fund-holdings-nport published nothing for seventeen days; the same morning could have stopped all fifteen datasets at once. The version is now chosen deliberately, and upgrading it is a commit where somebody also fixes whatever it finds.
