Replace intervention/image

[driesvints]

We can't seem to upgrade to v3 because they removed the ability to output images as responses: https://image.intervention.io/v3/introduction/upgrade

We'll need to figure out a new way to generate social images.

@driesvints I found a way around this using laravel's response(). The solution works you can try the PR code #1189 and let me know what you think of the approach.

I will also write tests for this code because currently it's not tested. (I don't know how to test dynamic images but hopefully will figure out soon 😅)
