authors list does not emit correctly for pyproject formatting

Reposted from tox-dev/pyproject-fmt#288

uv tool install pyproject-fmt
pyproject-fmt
>>> pyproject-fmt (2.5.0)

My pyproject file:

[project]
name = "my-app"
description = "My app"
version = "1.13.1"
requires-python = "<3.14,>=3.12"
[[project.authors]]
name = "Joe Blogs"
email = "[email protected]"

After running pyproject-fmt pyproject.toml

[project]
name = "my-app"
version = "1.13.1"
description = "My app"
authors.email = "[email protected]"
authors.name = "Joe Blogs"
[[project.authors]]

classifiers = [
  "Programming Language :: Python :: 3 :: Only",
  "Programming Language :: Python :: 3.12",
  "Programming Language :: Python :: 3.13",
]
requires-python = "<3.14,>=3.12"

There is a broken [[project.authors]] field.
