Audio: Ensure progress is reset in onEnded().

[Jian-Nam]

Issue Description:

The play method of the audio object in Three.js sets the starting point based on the current progress. The progress is updated only when the pause or stop methods are called.

Currently, when pause is executed during playback, the progress is set to the pause point. If the audio is played to the end from that point, the onEnded event is triggered, and the audio stops. However, if playback is restarted after this, the onEnded event does not update the progress. As a result, the audio restarts from the previous pause point rather than the actual start of the audio.

Proposed Solution:

This behavior is unintuitive and can lead to unexpected behavior. To resolve this issue, I modified the onEnded method to execute the stop method, which ensures that progress is updated correctly.
