Fix command in vm-generalized-image-version.md

[koudaiii]

Why

from https://learn.microsoft.com/en-us/azure/virtual-machines/vm-generalized-image-version?tabs=cli%2Ccli2%2Ccli3%2Ccli4#rbac---shared-from-another-tenant

This command does not work. Please take a look at it below.

$ az group create --location --resource-group $resourcegroup
argument --location/-l: expected one argument

Examples from AI knowledge base:
az group create --location westus --resource-group MyResourceGroup
Create a new resource group in the West US region.

az group create --location westeurope --resource-group MyResourceGroup --tags {tags}
Create a new resource group. (autogenerated)

az account list-locations
List supported regions for the current subscription. (autogenerated)
