6bd55b54 - Fix [core/GLIGEN]: TypeError when iterating over 0-d tensor with In-painting mode when EulerAncestralDiscreteScheduler is used (#5305)

Fix [core/GLIGEN]: TypeError when iterating over 0-d tensor with In-painting mode when EulerAncestralDiscreteScheduler is used (#5305) * fix(gligen_inpaint_pipeline): :bug: Wrap the timestep() 0-d tensor in a list to convert to 1-d tensor. This avoids the TypeError caused by trying to directly iterate over a 0-dimensional tensor in the denoising stage * test(gligen/gligen_text_image): unit test using the EulerAncestralDiscreteScheduler --------- Co-authored-by: zhen-hao.chu <zhen-hao.chu@vitrox.com> Co-authored-by: Sayak Paul <spsayakpaul@gmail.com>
