fixbug: Expand sentence-ending punctuation check in _create_statements method

[Jeff-67]

Description

This pull request addresses an issue where non-English punctuation (e.g., "。", "！") was not properly handled in the _create_statements function, causing sentences in languages like Chinese to be ignored and potentially leading to incorrect faithfulness scores.

Changes Made

Updated the condition:

if sentence.strip().endswith("."):

to

if sentence.strip().endswith(('.', '。', '!', '！')):

This ensures that sentences with non-English punctuation are included in the processing.

Impact

This change allows the system to correctly process sentences in languages like Chinese, preventing empty sentences_with_index variables and ensuring accurate faithfulness scores.
