[gnome-builder/wip/gtk4-port: 1053/1774] plugins/sysprof: allow opening syscap from project-tree

[Christian Hergert <chergert src gnome org>]

commit 88880e65231568e238f05b9ff6feb39da13c45f6
Author: Christian Hergert <chergert redhat com>
Date:   Tue May 17 15:47:07 2022 -0700

    plugins/sysprof: allow opening syscap from project-tree
    
    And anywhere else using the generic open interface of the workbench. Now
    that we have an IdePage for sysprof captures, we can just display one of
    those when opening.
