'insight' package description is wrong

[monnerat]

The insight package (https://apps.fedoraproject.org/packages/insight) is a gdb debugger gui frontend, not a medical image library. In addition, it has no relationship with the InsightToolkit* packages.

Name        : insight
URL         : https://www.sourceware.org/insight/
Summary     : Graphical debugger based on GDB
Description :
 Insight is a tight graphical user interface to GDB written in Tcl/Tk.
It provides a comprehensive interface that enables users to harness
most of GDB's power. It's also probably the only up-to-date UI for
GDB version 8.x.

Thanks for fixing.
