`Test-SqlDscIsAgentAlert`: Command rename proposal

[johlju]

Command proposal

Suggest renaming the command Test-SqlDscAgentAlert to Test-SqlDscIsAgentAlert for greater clarity and consistency with naming conventions. The new name better reflects that the command checks if an agent alert exists, rather than performing generic tests. This change will help users understand the purpose of the command more easily.

Proposed parameters

n/a

Special considerations or limitations

Renaming the command will be a breaking change for users who rely on the old name (Test-SqlDscAgentAlert). Proper deprecation notices and migration guidance should be provided. Update documentation and examples throughout the module to reflect the new name. We could use the old name as an alias.

This command should not handle validate properties, that has to move into the class-based resource.

Also the New-SqlDscAgentAlert should call test command instead of:

        # Check if alert already exists
        $existingAlert = Get-AgentAlertObject -ServerObject $ServerObject -Name $Name
