toml-sort modify files even when already well formatted

[manuelteillet]

Describe the bug

Running toml-sort -i on a well formatted file updates its last modified date, confusing treefmt --ci

To Reproduce

Steps to reproduce the behavior:

1. run treefmt on a .toml file with toml-sort configured to ensure it is well formatted
2. run treefmt --ci

treefmt --ci fails with ERRO file has changed ... showing different modification times

Expected behavior

treefmt --ci ends with no error

System information

toml-sort version 0.23.1
