Enhance for devtest ESE clarity

We have customers provisioning devtest ESU licenses incorrectly, getting billed and requesting a refund because they didn't fully understand the documentation.  I made some edits to existing verbiage in this article in attempt to improve the clarity on how devtest licensing works.

 There are some scenarios in which you may be eligible to receive Extended Security Updates patches at no additional cost. Two of these scenarios supported by Azure Arc are (1) [Dev/Test (Visual Studio)](/azure/devtest/offer/overview-what-is-devtest-offer-visual-studio) and (2) [Disaster Recovery (Entitled benefit DR instances from Software Assurance](https://www.microsoft.com/en-us/licensing/licensing-programs/software-assurance-by-benefits) or subscription only). Both of these scenarios require the customer is already using Windows Server 2012/R2 ESUs enabled by Azure Arc for billable, production machines.

-You have 8 Windows Server 2012 R2 Standard instances, each with 8 physical cores. 6 of these Windows Server 2012 R2 Standard machines are for production, and 2 of these Windows Server 2012 R2 Standard machines are eligible for free ESUs through the Visual Studio Dev Test subscription.

You should link this regular, production ESU license to your 6 production servers. Next, you should use this existing license, not add any more cores or provision a separate license, and link this license to your 2 non-production Windows Server 2012 R2 standard machines. You should tag the license and the 2 non-production Windows Server 2012 R2 Standard machines with Name: “ESU Usage” and Value: “WS2012 VISUAL STUDIO DEV TEST”.
