Disable local auth for the cosmos db (S360 item)

[v-rachitsh]

Description

In provision-deploy.yml, the New-AzCosmosDBAccount call does not include the -DisableKeyBasedMetadataWriteAccess or a way to disable local auth. The ARM template at default-azuredeploy-docker.json has "disableLocalAuth": true hardcoded, but this template is not used by the PR provisioning pipeline — the PR pipeline uses the PowerShell New-AzCosmosDBAccount cmdlet directly, which defaults to local auth enabled.
