Display source of errors when copied to clipboard

## Bug Description

In the support forums users often copy any errors encountered via the copy to clipboard feature recently added to the plugin. In many cases it's not known whether these issues occur from within the Site Kit admin panel or via the admin toolbar (as per the image below)


_Example WP Rocket minifcation conflict above_

If there is a way to indicate where this error occurs this would be a great improvement in identifying plugin related conflicts with combining of assets or minification on the front end. Additional flags that could be included when copied to the clipboard could include:
**Source**: admin toolbar || dashboard
**Module**: Search Console || Analytics || AdSense
