keep the original behavior, pause animation playback in the editor

Re: #

Changelog

• Previously, the playback of Spine animations was controlled in the update function based on EDITOR_NOT_IN_PREVIEW to determine whether playback was allowed. This approach caused issues with the preview functionality. To resolve this, the playback control has been changed to depend on the paused state. In order to maintain the original behavior, this PR has been added to ensure that animations do not play in the editor environment.
