Unstable formatting for [tool.ruff.lint] and [tool.ruff.lint.isort]

[hugovk]

Running pyproject-fmt 2.0.3 on the TOML below for the first time reformats it. That's fine, it was last formatted with 1.x.

But if I run it again it will either:

• do nothing
• Move [tool.ruff.lint.isort] below [tool.ruff.lint]
• Move [tool.ruff.lint.isort] back above [tool.ruff.lint]

We can see in hugovk/norwegianblue#212 that pre-commit.ci ran once to reformat, but then failed on its own changes.
