### Description

`/hello/world` is not a valid assembly name, but is accepted as one in .NET 10

### Reproduction Steps

```csharp
new AssemblyName("/hello/world")
```

### Expected behavior

System.IO.FileLoadException: The given assembly name was invalid.

### Actual behavior

Returns an instance of `AssemblyName`

### Regression?

In .NET 8 the parser would discard such a name.
