To Reproduce

Step-by-step reproduction instructions

1. Install the plugin
2. Add a comment block in a post template
3. Check the site when not logged in.

Expected results

1. Excpected not to see a warning

Actual results

1. A warning is thrown.

Even though it should maybe only render for logged in admins, the core/comment-edit-link is rendered for everybody in the front-end. Albeit not displaying anything, there's still an empy <div> showing up.

Because the block is rendered, the code on line 128 in hacks.php passes
if ( isset( $block['blockName'] ) && $block['blockName'] === 'core/comment-edit-link' ) { but the preg_match on line 129 won't find a match resulting in a warning on line 131.
