* feat: Introduce hapi-fhir-client-apache-http5 module for Apache HttpClient 5 support
- Added a new module `hapi-fhir-client-apache-http5` to provide HAPI FHIR Client functionality using Apache HttpClient 5.
- Supports gradual migration from HttpClient 4 to HttpClient 5.
- Aligns with Spring Boot 3.0's adoption of HttpClient 5, enabling consistent HTTP client configuration for users of both libraries.
Key Changes:
- Integrated Apache HttpClient 5 for modern, high-performance HTTP requests.
- Ensured compatibility with existing `hapi-fhir-client` and `hapi-fhir-client-okhttp` modules.
- Added basic tests to validate functionality and coexistence of HttpClient 4 and 5.
Impact:
- Non-breaking change; the new module can be adopted independently.
- Facilitates eventual migration of HAPI FHIR to HttpClient 5 across the codebase."
* Add new error codes to the apache-httpclient5 client module.
