Twenty Twenty: Hide extraneous elements in print.css

[kjellr]

Twenty Twenty hides many elements in the print view (e.g. the comments form, site navigation, site logo, etc.). There are still a few remaining elements that make sense to be removed too:

• Category. This feels like an odd lead-in to the page in a printed context. In most cases, this is primarily useful for viewing more posts in that category.
• Comment Count. The theme hides the comments in the print view, so I'm not sure that it makes sense to keep the comment count here.
• Previous/Next posts pagination.

(In the following screenshots, the Jetpack likes + shares should be hidden too, but that may be something that the Jetpack plugin should handle itself.)

Thanks, @hareesh-pillai, this patch works in my testing. ✅

In 50976:

Twenty Twenty: Hide some elements for print that are not useful in that context.

This adds the comment count, previous/next posts navigation, and category link list to the list of elements hidden from the print context.

Props kjellr, hareesh-pillai, poena.
Fixes #50433.

In addition to the three elements mentioned in the ticket description, changeset [50976] also hides the post/page Edit link (which is a good idea).

@sabernhardt Ah yes, thanks for calling that out here. I meant to add that to my commit message, and it slipped my mind.
