`prettier-plugin-toml` Crashes When Formatting a TOML File

[vivodi]

When attempting to format a pyproject.toml file, prettier fails with a panic error.

To Reproduce:

1. Create a pyproject.toml file with the following content:

   [project.gui-scripts]
   flexget-headless = "flexget:main"  # This is useful on Windows to avoid a cmd popup

2. Run the following command in your terminal:

   npx prettier --write pyproject.toml

Expected Behavior:

The TOML file should be formatted successfully without any errors.

Actual Behavior:

The command fails with the following error message and stack trace:

pyproject.tomlpanicked at /Users/JounQin/Workspaces/GitHub/taplo/crates/taplo/src/formatter/mod.rs:684:25:
assertion failed: entry.comment.is_none()
