Fixing visualization code for object detection to support both types of bounding box. (#27842)
* fix: minor enhancement and fix in bounding box visualization example
The example that was trying to visualize the bounding box was not considering an edge case,
where the bounding box can be un-normalized. So using the same set of code, we can not get
results with a different dataset with un-normalized bounding box. This commit fixes that.
* run make clean
* add an additional note on the scenarios where the box viz code works
