Azure Authentication Token of the webapp expires after 24h

[harsha-chamarthi]

Describe the bug
Azure Authentication token generated by the webapp expires after 24h, which is causing the VM deletion and creation to fail. https://github.com/liatrio/terraform-azure-github-runner/blob/main/app/runner-controller/azure/credentials.js, Azure authentication credentials are generated by this file but it fails to refresh the authentication token upon expiry which is 24 hours. For now as a workaround restarting the webapp refreshes the token

See error:
{"error":{"code":"ExpiredAuthenticationToken","message":"The access token expiry UTC time '6/9/2023 1:31:20 PM' is earlier than current UTC time '6/9/2023 4:48:41 PM'."}}},"details":{"error":{"code":"ExpiredAuthenticationToken","message":"The access token expiry UTC time '6/9/2023 1:31:20 PM' is earlier than current UTC time '6/9/2023 4:48:41 PM'."}}}

Expected behavior
Refresh the authentication token upon expiry.
