antctl.exe fails to run on Windows VM due to missing in-cluster configuration

[XinShuYang]

Describe the bug
Running antctl.exe on a Windows VM results in an error. The same command works fine when executed inside a Windows pod.

To Reproduce

1. Run antctl.exe supportbundle on a Windows Node.
2. Observe the error output.

Expected
The command antctl.exe supportbundle should execute successfully on the Windows VM, similar to how it works inside the Windows pod.

Actual behavior
When executing antctl.exe on a Windows VM, the following error is returned:

PS C:\k\antrea\bin> .\antctl.exe supportbundle  
Error: error when creating system client: unable to load in-cluster configuration, KUBERNETES_SERVICE_HOST and KUBERNETES_SERVICE_PORT must be defined  

Versions:
Antrea v2.1

@XinShuYang have you tried to define the KUBECONFIG env and rerun? I think this is expected when there is no right config file.

@XinShuYang can you prioritize the bug fix for this issue in Antrea 2.3?
