Fix minikube image load on windows (#20529)

[james-world]

fixes #20529

getWindowsVolumeNameCmd uses the deprecated wmic.exe, this breaks minikube image load on newer installs of windows. Whilst wmic.exe can be added, it will be removed from Windows 11 soon.

See here for details.

This fix replaces the use of wmic.exe with a call to the Powershell equivalent.

Hi @james-world. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

Can one of the admins verify this patch?

[gabrielgbs97]

If powershell.exe is not available in PATH (it should be...) it can be discovered via SystemRoot env variable:
'%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe

[james-world]

OK, sorry for the hiatus - been busy at work. @medyagh I've removed the fallback as discussed and added code to robustly discover Powershell.exe, using the cited approaches.

[medyagh]

thank you @james-world, let me ask @bobsira for last approve and then we can merge it
@bobsira can you plz test this on windows and see if it fixes the issue?

[bobsira]
