.Net: Fix error for System.Memory.Data 6, upgrade packages dependenci…

…es (#9454)

### Motivation and Context

This add a small fix when using SK with `System.Memory.Data 6.0.0`.

This bug happens when updating the `Azure.Core` to
[1.44.0](https://www.nuget.org/packages/Azure.Core/1.44.0) which
requires `System.Memory.Data` of 6 or above that introduce an error when
attempting to `.ToString()` on an empty `BinaryData` object.
