This changeset deactivates the download authenticity message by disabling package signature verification, at least until software signing is fully implemented on wordpress.org. The provided message had no actionability and only led to more support. Props jipmoors, afercia, bridgetwillard, s0what, rajinsharwar, audrasjb, johnbillion, peterwilsoncc. Fixes #47315. Built from https://develop.svn.wordpress.org/trunk@58319 git-svn-id: http://core.svn.wordpress.org/trunk@57776 1a063a9b-81f0-0310-95a4-ce76da25c4cd
