No user feedback if 0 regions found in inspect resource command

[AndrewTwydell]

Describe the bug

When inspecting a resource from the command palette, and you're setting the region to use, if you select a CICSplex with no regions in, an empty quickpick is provided.

Expected and actual results

Somehow be informed there are no regions present. An entry in the quickpick saying "No regions found"? An info message?

Something to show the user it's not still doing something, but it's just not found anything.
