This includes the packages that match the Gutenberg 9.2 Release. It is going to be the last block-editor features update for WordPress 5.6. It also updates the block-supports code base to the latest APIs. Props isabel_brison, noisysocks, desrosj. Fixes #51570. Built from https://develop.svn.wordpress.org/trunk@49226 git-svn-id: http://core.svn.wordpress.org/trunk@48988 1a063a9b-81f0-0310-95a4-ce76da25c4cd
