WordPress/wp-admin/update-core.php
Gary Pendergast 7e33702830 Plugins: Add plugin icons to the plugin list tables. 
To mirror theme list table behaviour, the plugin icon now appears next to plugins in the plugin list tables. For plugins that don't have an icon, or non-W.org plugins, a fallback dashicon is shown.

Props melchoyce, afercia, paulwilde, pento, obenland.
Fixes #30186.
