* Update Picture.astro
the image variable of getPicture contains a width and height property, which we usually require. In this case, the image is wrapped in a picture tag and the img tag itself should not have a width and height property as this will break the responsiveness of the image provided by the picture tag.
* added changeset
* fixing SSG picture tests that were expecting img dimensions
