You need to edit the code inserted with such a tag in Joomla. Where to look, what to edit?

Question

Joomla

You need to edit the code inserted with this tag in Joomla take.ms/tTA2R take.ms/XUl4X
The whole project combed through the content search - no results.
I looked here /libraries/joomla/document/html/renderer/head.php. There's nothing there. It turns out that somewhere in the admin panel you need to look.
I looked at take.ms/a7zih in the templates - there is nothing.
Someone faced such a problem?
