Make all images for clean architecture chapters smaller if too big

There are instances of images which are too big because markdown stretches them by default.

Find all such instances and use regular HTML to limit the width of the pictures in order for them to look better.

One type of problem is that often times, images appear on the same line as the previous row as in here:

This can be fixed by putting a whitespace between the picture and the line before it.

Another problem is that often times, some images are rendered too big by default. example:

I think this one can be reduced to be at most 300 pixels wide
