fix: Pass 'c_limit' param to hi_def URL

[petesfrench]

Done

• Adds the 'c_limit' flag to the image width and height on hi-def image which limits the max width and height of the image to it's intrinsic width and height, see docs. This is because the hi-def tag doubles the width and height, sometimes leading to the image size being set larger than the original image size, and making the quality worse

QA

• Open the demo I set up on c.com that references this branch in it's requirements
• Compare the image quality to production and see they are the same
