fix(test): Make hostname test work in container environments

* Card ID: CCT-994

Remove container skip condition and add container-specific logic that:
- Modifies hostname files in archive instead of system hostname
- Uploads modified archive using --payload and --content-type
- Verifies archive modification and upload success

     :title: Verify Insights Archive Updates Host Information
     :description:
-        Ensure that updating files within an Insights Archive reflects
-        the correct host information, such as hostname, in the Inventory
+        Ensure that updating files within an Insights Archive works correctly.
+        In regular systems, test hostname changes in Inventory.
+        In containers, test archive modification and upload workflow.

         1. Register the system with insights-client and confirm data upload
-        2. Change the system hostname
+        2. Change the system hostname (non-containers) or modify archive files

-        4. Retrieve host data from Inventory and verify fqdn

+            or successful processing (containers)

-        4. The fqdn in the Inventory matches the updated hostname
+        4. In non-containers, the FQDN in Inventory matches the updated hostname.
+            In containers, the archive upload and processing succeeds.
