Add file for strong naming assembly

If you use `sn -T` on the version 1.3.0 RabbitMQ dll, you get this:

```
lib\net6.0> sn -T .\RabbitMQ.Stream.Client.dll

Microsoft (R) .NET Framework Strong Name Utility  Version 4.0.30319.0
Copyright (c) Microsoft Corporation.  All rights reserved.

.\RabbitMQ.Stream.Client.dll does not represent a strongly named assembly
```

Actually do the signing correctly. Thanks for double-checking @Zerpet

Add `AltCoverStrongNameKey` to fix builds using AltCover
