refactor: Update language descriptions for clarity in multiple components

- Changed the language description in FasterWhisperSettingWidget, LanguageSettingDialog, WhisperAPISettingWidget, and WhisperCppSettingWidget to provide clearer context about the source language detection.
- Updated text to specify that the language is automatically detected based on the first 30 seconds of audio, enhancing user understanding.
