New AssemblyDependencyResolver codepath differs from legacy behavior on version mismatch

In a new project create a `nuget.config` with these contents:

```xml

```

Then run `dotnet restore` using .NET SDK `7.0.100-preview.4.22222.1`.

Actual behavior:

```sh-session
❯ &"C:\Users\raines\Downloads\dotnet-sdk-7.0.100-preview.4.22222.1-win-x64\dotnet.exe" restore
Determining projects to restore...
S:\repro\dotnet\sdk\issues\23498\23498.csproj : error NU1301: Unable to load the service index for source https://api.n
uget.org/v3/index.json.
Retrying 'FindPackagesByIdAsyncCore' for source 'https://example.com/FindPackagesById()?id='Microsoft.NETCore.App.Ref

Password decryption is not supported on .NET Core for this platform. The following feed uses an encrypted password: '
foo'. You can use a clear text password as a workaround.
Windows Data Protection API (DPAPI) is not supported on this platform.
```

This is effectively a recurrence of https://github.com/dotnet/sdk/issues/23498 caused by #7520--the new `AssemblyDependencyResolver` adopts the greater-than-or-equal version check much like #6993 wants, but that causes the NuGet scenario regression.
