Locks list incorrect on plugin directory page

[daisyo]

The blocks listed on some plugin directory pages don't appear to line up with what is available when the plugin is installed.

The example I identified is ​https://wordpress.org/plugins/layout-grid/

There are technically two blocks but one is only accessible as an inner block and they do have different names and labels in the plugin code.

For reference:

Block registration: ​https://github.com/Automattic/block-experiments/blob/master/blocks/layout-grid/index.php#L4

Block definitions: ​https://github.com/Automattic/block-experiments/blob/master/blocks/layout-grid/src/index.js
