Bug in "STM32CubeExpansion_Cloud_AZURE_V1.2.0"

Hello,

In the new version of "STM32CubeExpansion_Cloud_AZURE", file "comodo_baltimore.pem" does not exist. The content of this file sets the TLS root CA certificates.

Use Middlewares\Third_Party\azure-iot-sdk-c\certs\usertrust_baltimore.pem instead of comodo_baltimore.pem.
