createOptimizedPicture should set img width/height attributes #169
Description
Expected Behaviour
the img element generated by createOptimizedPicture should contain width/height attributes.
Actual Behaviour
the current implementation of createOptimizedPicture generates images without specifying width/height attributes - google pagespeed complains about this, and it often leads to cumulative layout shift (CLS).
please note that the actual width/height of the source image is not part the URL that is used as src input parameter, and is not contained in the data generated by query-index.
