[docs] box_convert seems to support batch-less mode as well, but this is not documented

🐛 Describe the bug

It seems that box_convert does support Tensor[4] arguments as well, but this is not documented. This is a useful mode to support, so would be nice if this was documented

@vadimkantorov Thanks, a PR is welcome.

Yep, it is supported 😃
Just a note that other ops such as box_area, box_iou, etc don't support the same.
I'm not sure if this functionality should be extended.
