Install fails on .NET 9

[MeikelLP]

The command dotnet tool restore fails in our pipeline.
dotnet-tools.json:

{
  "version": 1,
  "isRoot": true,
  "tools": {
    "generateaspnetcoreclient.refit": {
      "version": "3.0.0",
      "commands": [
        "dotnet-generate-client"
      ],
      "rollForward": false
    }
  }
}

Unhandled exception: Microsoft.DotNet.ToolPackage.ToolConfigurationException: Settings file 'DotnetToolSettings.xml' was not found in the package.

I found a similar issue: chucknorris/roundhouse#421

Thus I think this is the package's fault and not something I can fix myself. From what I can see you just need to add an "empty" DotnetToolSettings.xml

Additional note:

This issue happened when installing the tool with net8 SDK which is not supported I know but the message is still confusing
