Basic Quarkus 3 toleration

[holly-cummins]

Quarkus 3 brings two major changes - the javax/jakarta namespace change, and a change to classloading. Quarkus 2 core defined many pact modules to be parentfirst. In Quarkus 3, that will be done by this extension. The Quarkus 3 kotlin extension also stopped loading kotlin parent first.

Consumer
I was able to remove all the parent-first dependencies for the consumer.

Provider
For the provider, oddly, I had it working with a single parent-first dependency (one pact library) in December, but now I needed the full set. I think that's because of the reversion of quarkusio/quarkus#29785 between when I first did the work and now.

I will continue working to see if I can reduce it down to a minimal set, or having both extensions in the same project will be a problem. Ideally, the provider would work without any parent first dependencies, but that is a bigger piece of work.

I did have to disable one test, and have raised #73 to reflect the failing test, but I think #73 is not a serious issue.

Also, with the classloading changes in Quarkus 3, it looks like neither quarkusio/quarkus#30238 nor quarkusio/quarkus#30383 are needed for consumer tests to work in dev mode.
