Sharepoint-Three-VM repo has bad platform image name in provisioningSQL.json

GitHub\azure-quickstart-templates\sharepoint-three-vm\provisioningSQL.json

### Issue Details
The file provisioningSQL.json has a bad platform image name. This is the update that needs to be made:

"storageProfile": {
"imageReference": {
"publisher": "MicrosoftSQLServer",
"offer": "SQL2016-WS2016",
"sku": "SQLDEV",
"version": "latest"

### Repro steps (*if necessary, delete otherwise*)
1. Deploy to Azure
2. Complete Peramters
3. Deployment will fail with the error that the template image doesn't exsist for the 2014SQL

Open sharepoint-three-vm/provisioningSQL.json and inspect the storageProfile imageReference values. Compare the referenced SQL Server image with the image expected by the template, then deploy the SharePoint three-VM template to confirm provisioning no longer fails because the platform image is missing.
