Look up module name as well, when searching with Admin Toolbar Search

Problem/Motivation

It seems like only the path of a module is indexed and used in Admin Toolbar Search.

So for example, a module such as Glossify → which "Configure" path is /admin/config/content/formats will not pop up, if you do a search for "gloss".

Steps to reproduce

1. Install Glossify and Admin Toolbar Search module
2. Search for Glossify with Admin Toolbar Search and get no results

Proposed resolution

I assume it's because only the path is indexed, or searched in, so perhaps we could include the module title as well, when doing a search?

Remaining tasks

User interface changes

API changes

Data model changes
