revert: "feat(web/panettone): Allow requesting JSON"

This reverts commit 77c09076ec.

Reason for revert: It doesn't work - attempting to request any of the pages now gives:

[ERROR]] No keys match in SWITCH. Testing against
         "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9"
         with EQUAL.
