Hi.

I think that #67 added a bug where it keep adds a newline.

After several runs, I get the following:

[[tool.mypy.overrides]]
module = "vendor.*"
ignore_errors = true

















[tool.ruff]
exclude = [
  ".git",

Message after a run:

$ pyproject-fmt pyproject.toml
--- pyproject.toml

+++ pyproject.toml

I'll gladly provide more if you need it.
