refactor: Update loadedTime getter in Artplayer

The code changes update the loadedTime getter in Artplayer to handle different scenarios. The getter now checks for the presence of the loadedTime property in the video element and returns it if available, otherwise it falls back to the previous logic of retrieving the buffered end time. This update improves the reliability and compatibility of Artplayer's loadedTime functionality.
