WLS quick start: support non-empty resource group.

[galiacheng]

This pull request includes updates to the articles/virtual-machines/workloads/oracle/weblogic-server-azure-virtual-machine.md file to correct the date and improve the clarity of instructions for deploying WebLogic Server on Azure Virtual Machines.

Documentation updates:

• Updated the ms.date metadata to reflect the new date 12/23/2024 instead of 10/08/2024.
• Clarified the instructions for creating a new resource group by removing the redundant statement about the offer needing to be deployed in an empty resource group.
