Add extra tests to test if the nuget version implementation is correct

What are you trying to accomplish?

Add extra tests to test if the current nuget version implementation, in ruby, is correct.

Nuget have a version identifier spec and I'm trying to confirm if our current version implementation abides by this specification.

@brettfo I was just testing the current version.rb in nuget and some of the ruby tests I added are failing so I know it does not abide by the nuget version spec.

I'm also aware of the C# version implementation here but I'm not entirely sure if we're using the ruby version or the C# version, or indeed, how the two work together. Could you please clarify.

From what I've understood so far, I do not need to update the ruby version implementation to match the nuget version specification as that is already being done in the C# implementation.
