var adoSynonyms = map[string]string{

At minimum, add "Authentication" as a synonym for "fedauth".

Also, update the azuread package to support the same set of Authentication name values as ADO.Net in addition to the names it already supports as values for the fedauth parameter.

The name values ADO.NEt supports are:

 const string SqlPasswordString = "Sql Password";
        const string ActiveDirectoryPasswordString = "Active Directory Password";
        const string ActiveDirectoryIntegratedString = "Active Directory Integrated";
        const string ActiveDirectoryInteractiveString = "Active Directory Interactive";
        const string ActiveDirectoryServicePrincipalString = "Active Directory Service Principal";
        const string ActiveDirectoryDeviceCodeFlowString = "Active Directory Device Code Flow";
        internal const string ActiveDirectoryManagedIdentityString = "Active Directory Managed Identity";
        internal const string ActiveDirectoryMSIString = "Active Directory MSI";
        internal const string ActiveDirectoryDefaultString = "Active Directory Default";
        internal const string ActiveDirectoryWorkloadIdentityString = "Active Directory Workload Identity";
