Describe the bug

When I generate a Pact-compatible consumer contract based on WireMock.Net traffic, for every interaction, the contract contains an entry for providerState, but not for description.

Yet, it is the description that will show up in PactFlow. It is now empty:

Expected behavior:

I expect the value supplied in the WithTitle() method to be mapped to a field called description in the Pact-compatible contract, not to a field called providerState.

As far as I can see, It's OK to simply change the mapping and leave out the providerState field altogether, as that isn't used in bidirectional contract testing, anyway. WireMock in Java does the exact same thing (image shows contract generated by WireMock in Java, you can ignore the key and pending fields, too):

Test to reproduce

N/A

Happy to dive into this and create a PR myself, if you would like me to, @StefH.

@basdijkstra
Can you make a PR.

I think you need to change this code:
https://github.com/wiremock/WireMock.Net/blob/master/src/WireMock.Net.Minimal/Serialization/PactMapper.cs#L45

So in case a description is set on the mapping use that one, else use the title and remove providerState mapping.
