Issue

When generating poetry.lock in mixed environments (e.g. Windows and Linux), CRLF gets replaced by LF and vice versa. This had already been reported and supposedly fixed before (#1488), but probably regressed during the introduction of tomli (#6562). I couldn't find any special treatment for line endings of poetry.lock in poetry's code.
