dotnet format does not respect the .NET install location

I manage my own .NET installations and have the `dotnet` command aliased to the directory where I keep my installations. This works perfectly for `dotnet run`, `dotnet build`, `dotnet pack` etc. When running `dotnet format` however, I get the following error message:
```
No .NET SDKs were found.

Download a .NET SDK:
https://aka.ms/dotnet/download

Learn about SDK resolution:
https://aka.ms/dotnet/sdk-not-found
Unable to locate MSBuild. Ensure the .NET SDK was installed with the official installer.
```

I am using macOS 13.4.1 with an M1 Pro.
