remove managedIdentityCredential call

[pl-jankowskimichal]

just trying out an idea here. not a proposla at this point..

I actually have no idea if this works but I tried setting some extra env vars like:

 {
      "name": "AZURE_TOKEN_CREDENTIALS",
      "value": "WorkloadIdentityCredential"
  },
  {
      "name": "AZURE_AUTHORITY_HOST",
      "value": "https://login.microsoftonline.com/"
  },
 

with and without setting --azure-user-assigned-identity-id to ""
and I'm still getting the same error

{"error":"azure.BearerAuthorizer#WithAuthorization: Failed to refresh the Token for request to https://management.azure.com/subscriptions/<REDACTED>/providers/Microsoft.Network/virtualNetworks?api-version=2021-08-01: StatusCode=400 -- Original Error: adal: Refresh request failed. Status Code = '400'. Response body: {\"error\":\"invalid_request\",\"error_description\":\"Identity not found\"} Endpoint http://169.254.169.254/metadata/identity/oauth2/token?api-version=2018-02-01\u0026client_id=%22%22\u0026resource=https%3A%2F%2Fmanagement.core.windows.net%2F","level":"warning","msg":"Unable to synchronize Azure virtualnetworks list","subsys":"azure","time":"2025-10-23T08:17:10.926229744Z"}

adal is an old azure library
I'm still figuring out what is going on here
