fix: Hide cursor in print output

[juliusknorr]

Follow up to #5054 to make tests more stable by hiding the cursor that may be more or less transparent depending on the activity state.

Also it is not much useful in print view.

Thanks for the follow-up. Let me push two more commits in the hope they help:

• Set caret-color to transparent before doing the snapshot
• One more time update the screenshots

But looking at the screenshot diffs it rather seems like the whole rendering is not pixel-perfect and moves a few pixels up/down left/right between runs 🤔
