Uncheck all jars

### Description

I have a project with a huge number of dependencies with above 200+ jars supporting the project. For testing purposes I need to uncheck all imported jars in library window which I need to do manually for all the jars because I could not see a feature for unchecking all jars at once, So if there is a feature for unchecking all jars in one button click, It would be so helpful.

### Use case/motivation

I need a option to uncheck all the imported jars in library window.

Start by locating the NetBeans library window and its controls for imported JAR selection. The feature is done when a clearly available action unchecks all imported JARs at once; verify it with a project containing many dependencies.
