[BUG] fabric warehouse connection with service principal authentication fails with error "Unsupported creation method"

[pedrorebelo782]

🐛 What happened?

When attempting to create a Fabric connection to a Data Warehouse using Service Principal authentication, it's failing with error "Unsupported creation method. The creation method is not supported":

the respective block being used is as below:

{
 "credentialDetails": {
   "skipTestConnection": false,
   "connectionEncryption": "NotEncrypted",
   "credentials": {
     "tenantId": "<tenantId>",
     "servicePrincipalClientId": "<servicePrincipalClientId>",
     "servicePrincipalSecret": "<servicePrincipalSecret>",
     "credentialType": "ServicePrincipal"
   }
 },
 "displayName": "<displayName>",
 "connectivityType": "ShareableCloud",
 "connectionDetails": {
   "type": "Warehouse",
   "creationMethod": "Fabric.Warehouse",
   "parameters": []
 },
 "privacyLevel": "Organizational"
}

When checking this API - https://learn.microsoft.com/en-us/rest/api/fabric/core/connections/list-supported-connection-types?tabs=HTTP#connectioncreationmetadata - the method shows up as listed:

also, if we test changing to just "Warehouse" instead of "Fabric.Warehouse", the new error even mentions that "Fabric.Warehouse" is the supported value:

versions being used are: Terraform v1.11.4 and Fabric Provider v1.6.0.
