[BUG] dotnet location not respecting `existingDotnetPath`

Describe the Issue

dotnet installed in Program Files only has sdk 6, while I need 8. Without admin rights, it's not possible to install sdk 8 in it. So I'm trying to set a custom location for the dotnet SDK.

It seems like the new location is picked up but nuget still uses the dotnet.exe from PATH (which I can't modify since it's a system env var).

Specifically this line: Found installed dotnet location "C:\Program Files\dotnet\dotnet.exe" to load projects. is not respecting the custom location C:\Users\username\AppData\Local\dotnet-sdk-8.0.401-win-x64\dotnet.exe

Steps To Reproduce

SDK 6 installed at default location SDK 8 installed at a custom location vscode settings set:

{
  "dotnetAcquisitionExtension.sharedExistingDotnetPath": "C:\\Users\\username\\AppData\\Local\\dotnet-sdk-8.0.401-win-x64\\dotnet.exe",
  "dotnet.dotnetPath": "C:\\Users\\username\\AppData\\Local\\dotnet-sdk-8.0.401-win-x64",
  "dotnetAcquisitionExtension.existingDotnetPath": [
    {
      "extensionId": "ms-dotnettools.csdevkit",
      "path": "C:\\Users\\username\\AppData\\Local\\dotnet-sdk-8.0.401-win-x64\\dotnet.exe"
    },
    {
      "extensionId": "ms-dotnettools.vscodeintellicode-csharp",
      "path": "C:\\Users\\username\\AppData\\Local\\dotnet-sdk-8.0.401-win-x64\\dotnet.exe"
    },
    {
      "extensionId": "ms-dotnettools.csharp",
      "path": "C:\\Users\\username\\AppData\\Local\\dotnet-sdk-8.0.401-win-x64\\dotnet.exe"
    },
    {
      "extensionId": "ms-dotnettools.vscode-dotnet-runtime",
      "path": "C:\\Users\\username\\AppData\\Local\\dotnet-sdk-8.0.401-win-x64\\dotnet.exe"
    }
  ],
  "omnisharp.sdkPath": "C:\\Users\\username\\AppData\\Local\\dotnet-sdk-8.0.401-win-x64\\sdk\\8.0.401",
  "omnisharp.dotNetCliPaths": [
    "C:\\Users\\username\\AppData\\Local\\dotnet-sdk-8.0.401-win-x64\\dotnet.exe"
  ]
}

It should use C:\Users\username\AppData\Local\dotnet-sdk-8.0.401-win-x64\dotnet.exe.
