Support URL params inside the url of getting started samples definition

[eye0fra]

Describe the bug

Upon configuring the dashboard with a custom sample, it accurately presents the URL with parameters. However, it fails to process this information during workspace startup, akin to the Create Workspace functionality.

Che version

7.82@latest

Steps to reproduce

Adhere to the instructions for configuring the getting started samples outlined here: https://eclipse.dev/che/docs/stable/administration-guide/configuring-getting-started-samples/

Within the URL definition, include a URL with parameters, such as:

     {
        "displayName": "Example", 
        "description": "Example", 
        "tags": ["example"], 
        "url": "https://example.com/my-project.git?df=next/base/devfile.yaml"
      }

Click the generated icon in the dashboard to observe any errors produced by the dashboard.

Expected behavior

Same behaviour as the Create Workspace functionality.
