Cannot launch on Windows Server 2025 - Hyper V installed but not found

**Describe the bug**
After Installing Multipass on Server 2025 Datacenter you cannot run `multipass launch` with out getting the following error message

> launch failed: The Hyper-V Hypervisor is disabled. Please enable by using the following
> command in an Administrator Powershell and reboot
> Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-Hypervisor

In my case Hyper-V is running and installed and I have a Default Switch configured.

**To Reproduce**
How, and what happened?
1. Run `multipass launch --name Something`
2. Get
`launch failed: The Hyper-V Hypervisor is disabled. Please enable by using the following
command in an Administrator Powershell and reboot:
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-Hypervisor`

**Expected behavior**
A new instance to be launched.

**Additional context**
Add any other context about the problem here.

Reproduce `multipass launch --name Something` on Windows Server 2025 Datacenter with Hyper-V enabled, then inspect the attached `Multipass Export.txt` and the Hyper-V detection path. Done means Multipass recognizes the installed Hyper-V hypervisor and launches a new instance without the disabled-hypervisor error.
