Add integration test for ConvertTo-SqlDscEditionName command

[Copilot]

The ConvertTo-SqlDscEditionName command was missing integration test coverage to ensure reliability in real environments. This PR adds comprehensive integration tests that validate the command's functionality without requiring SQL Server connectivity.

What's Added

Integration Test Coverage (tests/Integration/Commands/ConvertTo-SqlDscEditionName.Integration.Tests.ps1):

• Tests all known edition IDs (SQL Server Developer: 2176971986, Power BI Report Server - Developer: 2017617798, Power BI Report Server - Evaluation: 1369084056)
• Validates unknown edition ID handling with fallback to "Unknown"
• Verifies output object structure (PSCustomObject with EditionId, Edition, EditionName properties)
• Tests parameter validation for UInt32 boundaries (0 to 4294967295)
• Ensures type consistency (UInt32 for EditionId, String for Edition/EditionName)

Pipeline Integration:

• Added test to Azure pipeline Group 2 alongside similar utility functions
• Tagged for SQL Server 2017, 2019, and 2022 integration runs

Testing

All 12 new integration tests pass, existing 3 unit tests continue to pass, and all 781 QA tests remain compliant. The integration test follows established repository patterns and provides real-environment validation for this utility command.

# Example test coverage
ConvertTo-SqlDscEditionName -Id 2176971986
# Returns: EditionId=2176971986, Edition="Developer", EditionName="SQL Server Developer"

ConvertTo-SqlDscEditionName -Id 99999  
# Returns: EditionId=99999, Edition="Unknown", EditionName="Unknown"

Fixes #2208.
