• Removed Dead Code: Deleted all implementations and tests related to PathParametersValidationService.
• Updated Logic: Introduced improved methods for path normalization and ambiguity detection in FlowValidationDomainService.
• Updated Tests: Adjusted and removed test cases to align with the new service. Deleted obsolete test resources related to the deprecated service.

Code Review

This pull request successfully replaces the deprecated PathParametersValidationService with FlowValidationDomainService, introducing a more robust path parameter validation logic that correctly handles OpenAPI path templating ambiguities. The new implementation is a significant improvement and correctly addresses the issue of rejecting valid OpenAPI specifications. I've provided a couple of suggestions in FlowValidationDomainService to further enhance the new logic's performance and readability. The removal of old code and tests is clean. Overall, this is a great enhancement.
