Thank your very much for your contribution. Your work is very appreciated. Unfortunately, the implementation is based on the WireMock 2 approach, but we'd like to traget WireMock 3. Maybe we can merge the most parts of this PR into X.0, but I would ask for a rework when targeting main. Thank you so much.

Edit: Ah my fault, you're targeting 0.x :-) Then I have just some minor comments.

yeah was going to make another one for Quarkus 3 + WireMock 3 :) thanks for the review!

@chberger addressed your concerns, I'll continue this work for WireMock 3 with a PR to the main branch next.
