Improve HttpError Body Recording

[ludorival]

Description:
This pull request enhances the error handling mechanism in the pact-jvm-mockk plugin by improving the way HttpError responses are recorded. Key changes include:

1. Addition of anError Function:

   • Introduced a new helper function anError to throw a PactMockResponseError with a detailed response body.
   • This replaces the direct usage of HttpClientErrorException.

2. Refactoring Interception Logic:

   • Refactored the interception logic by introducing interceptAndGet to ensure proper handling and returning of results or errors.
   • Simplifies the existing intercept method by delegating result handling to adapters.

3. Enhancement in Adapter:

   • Enhanced SpringRestTemplateMockkAdapter to handle PactMockResponseError and construct HttpClientErrorException with detailed error information.
   • Supports both the original and detailed error handling seamlessly.

4. Internal Changes:

   • Introduced errorResponse in PactMockKAnswerScope to capture error responses.
   • Added PactMockResponseError class to encapsulate error responses.

These changes aim to improve the expressiveness and clarity of HTTP error responses recorded during Pacts.
