Upgrade the Azure IoT certificate for CI/CD devices

[PradeepKiruvale]

Describe the bug Azure is replacing the Baltimore cyber trust cert with the Digi cert root certificate. Once replaced the thin-edge device should connect to the Azure IoT without any issue.

To Reproduce Try connecting to the "Azure cloud" using tedge connect az

Expected behavior Should connect successfully and publish the measurements.

Environment (please complete the following information):

• OS [incl. version]
• Hardware [incl. revision]
• System-Architecture [e.g. result of "uname -a"]
• thin-edge.io version [e.g. 0.1.0]

Additional context More information can be found here

I don't think we need something specific action rather than the doc change. https://thin-edge.github.io/thin-edge.io/html/tutorials/connect-azure.html#configure-the-device

sudo tedge config set az.root.cert.path /etc/ssl/certs/Baltimore_CyberTrust_Root.pem

And we can't do it right now, as they are going to apply it from February 2023.

In addition, as of now, we just need to check all self-hosted runners have DigiCert_Global_Root_G2.pem certificate in /etc/ssl/certs.
