fix: add imageWidth & imageHeight properties on Tile (#108)

The proposed change for the Tile component involves adding a feature to specify the width and height of the optional image. 
I added imageWidth & imageHeight optionnal properties to follow the imageUrl & imageAlt pattern.

I'll make another suggestion : introduce an imageProps object, similar to the existing linkProps object, which would provide greater flexibility and control over the image properties. 

I am open to discussing this further.
