Pushkin logo on npm

[jessestorbeck]

Currently, the logo doesn't display correctly for any pushkin packages on npm. I thought I fixed this the last few times I published updates, but it turns out the real problem is with their markdown parser and how it handles relative image paths (npm/marky-markdown#437). Replacing the img tag with this should do the trick:

<img src="https://raw.githubusercontent.com/pushkin-consortium/pushkin/master/pushkin_bw_w_text.png" height="400" width="450" alt="pushkin logo">

I made the change to worker in pushkin-consortium/pushkin-worker#29, but CLI, API, and client should have their readme updated accordingly. We can also ditch the images folder for each of these packages. In the case of CLI, "images/*" should be removed from the files property in package.json.

Note: since we moved to a mono repo the link given above throws a 404, the correct link for the image is:

<img src="https://raw.githubusercontent.com/pushkin-consortium/pushkin/main/docs/img/pushkin_bw_w_text.png" height="400" width="450" alt="pushkin logo">

@jessestorbeck @ayang21 I just fixed the image tags and opened Pr #266, once this is merge I can update the npm packages inside of main as I didn't want to npm publish from a branch
