Support for new format introduced with version greater 2.5

[albarralnunez]

What we need:
The plugin doesn't support versions of scw cli greater than 2.5

How to solve it:
Add a new URL to the set of URLs to test for downloading the artifact.

Considerations:
If the format keeps changing, a refactor of this part of the plugin would be required.
