Misleading error about WSLInterop

### Describe the bug

WSL 2.0, Ubuntu 24.04
az CLI version: 2.89.1

az login command reported misleading error that WSL interopt is disabled but it finally redirects to external browser and works as expected

### Related command

az login

### Errors

grep: /proc/sys/fs/binfmt_misc/WSLInterop: No such file or directory
WSL Interopability is disabled. Please enable it before using WSL.
grep: /proc/sys/fs/binfmt_misc/WSLInterop: No such file or directory
[error] WSL Interoperability is disabled. Please enable it before using WSL.

### Issue script & Debug output

On WSL interopt is enabled and working:
```
$cat /etc/wsl.conf
[interop]
enabled=true
appendWindowsPath=false

$echo $WSL_INTEROP
/run/WSL/725_interopls

$ls /proc/sys/fs/binfmt_misc
/proc/sys/fs/binfmt_misc/WSLInterop-late python3.12 register status

$cat /proc/sys/fs/binfmt_misc/WSLInterop-late
enabled
interpreter /init
flags: P
offset 0
magic 4d5a
```

### Expected behavior

az login should work without misleading error and correctly detect WSL interop

### Environment Summary

az cli: 2.89.1
WSL 2.0, Ubuntu 24.04
