Make desktop href configurable (or remove hardcoded value) to avoid navigation popup in Zowe v3

[dharunraj22]

Description

In Zowe v3, navigating within the application triggers a browser “Leave site?” popup due to a URL change between plugins.

Observed Behavior

The application initially loads from:

https://z2pub.pok.stglabs.ibm.com:14522/zlux/ui/v1/ZLUX/plugins/org.zowe.zlux.bootstrap/web/

When hovering over or clicking a file, the URL changes to:

https://z2pub.pok.stglabs.ibm.com:14522/zlux/ui/v1/ZLUX/plugins/org.zowe.zlux.ivydesktop/web/

Since the plugin segment changes from:
org.zowe.zlux.bootstrap → org.zowe.zlux.ivydesktop
the browser interprets this as navigation to a different location and displays a “leave site” popup.

This behavior does not occur in Zowe v2.

Root Cause Investigation

In v3 (staging/virtual-desktop/src/desktop.ts), the following statement is present:

baseUrl.setAttribute("href", ZoweZLUX?.uriBroker.desktopRootUri());

We tested removing this statement, and the issue no longer occurs.
Navigation works correctly and the browser popup does not appear.

This suggests that explicitly setting the base href to org.zowe.zlux.ivydesktop is causing the URL switch and triggering the browser behavior.

In v2, no such explicit href assignment exists.

@DivergentEuropeans and @1000TurquoisePogs , if it's possible we'd like to bring this up on the Web UI squad cal Thursday 6th March. A couple of the developers who are running into this issue on one of the IBM extender products are hoping to join as well.
