• Regenerates all code using the Microsoft Go Code Generator instead of AutoRest
• Updates the API version from 2021-04-01 to 2023-04-01
• Changes the module path to include /v2 suffix for proper Go module versioning
• Updates dependencies to newer versions
• Adds new types and fields per the 2023-04-01 API specification
