Add Short Descriptions for 'Testing Plugins' Widget

[ankitguptaindia]

I would like to propose an enhancement for the 'Testing Plugins' widget on the Tets P2. Currently, new visitors might face confusion regarding the purpose and usage of these plugins as there is no clear description provided.

Adding short and informative descriptions for this widget will help new users to understand the use of this plugin list.
Currently, it looks like this plugin list needs testing.

Benefit:
The proposed enhancement aims to reduce confusion and provide a more user-friendly experience, especially for newcomers to the site.

Expectation A description like "These plugins will help in testing of WordPress Core, plugins, and themes"
