az login inside containerapp code no longer working.

### Describe the bug

Before the CLI change to 'az login --identity' I 'az login --identity --username' to login and the run 'az aks get-credentials'

### Related command

```
string command = $"-c \"az login --identity --username {manageId} && az aks get-credentials --resource-group {buildInfo.resourceGroupName} --name {buildInfo.clusterName} --overwrite-existing\""; // Command to log in to Azure

// Create a process start info
ProcessStartInfo loginInfo = new ProcessStartInfo
{
FileName = "bash",
Arguments = command,
RedirectStandardOutput = true,
RedirectStandardError = true,
UseShellExecute = false
};

// Create and start the process
using (Process process = new Process())
{
process.StartInfo = loginInfo;
process.Start();

string output = process.StandardOutput.ReadToEnd();
string error = process.StandardError.ReadToEnd();

// Wait for the process to exit
process.WaitForExit();

// Check exit code
int exitCode = process.ExitCode;
if (exitCode == 0)
{
// Command executed successfully
Console.WriteLine("Command executed successfully");
Console.WriteLine($"Output: {output}");
}
else
{
// Command failed
Console.WriteLine($"Command failed with exit code {exitCode}");
Console.WriteLine($"Error output: {error}");
}
}

```
