Documentation: sprite_get_info().frame_info returns undefined for sprites with no elongated frames, which is not written in doc

[Furkan-Karabudak]

Description

sprite_get_info().frame_info returns an array containing the frames timing info, but for sprites with no elongated frames, it returns undefined. But this is not written in the documentation, this may cause the delusion that this variable always returns this array. Related: #6331
