Inclusion of freebsd RIDs causes restore error on vertical builds

[mthalman]

The changes in #18763 are attempting to update the SDK version that is used in the VMR. This is causing failures in the vertical builds:

The project.assets.json file shows that the net9.0 target framework has the Microsoft.NETCore.App.Host and Microsoft.AspNetCore.App.Runtime runtime packs listed as download dependencies for the freebsd RID. This causes an attempt to download these packages and it fails because they do not exist in the .NET engineering package feeds.

This inclusion of the freebsd RID into the SDK was introduced by this change: #18493
