azurerm_mssql_server - Fix issue where minimum_tls_version is being returned as None instead of Disabled

[sinbai]

Test case TestAccMsSqlServer_minimumTLSVersionDisabled failed with the error "minimum_tls_version cannot be removed once set, please set a valid value for this property." This is caused by the API returns the value of minimum_tls_version is None when the setting value of minimum_tls_version in tf config is disabled . Previously, the API would not return any value in this case. I assume that this is an API breaking change. An API issue has been filed to track it. Meanwhile, submitted this PR to fix the issue.

This was working up until last month and looks like a breaking api change. Can we open an issue on rest-api-specs and leave a comment here about it?
