OPEN-82: Replace CC0 license with Apache-2.0 and update CI workflows (#14)

- Updated project license from CC0 to Apache-2.0, ensuring files meet
the new licensing requirements.
- Replaced outdated Rust workflow with an improved CI pipeline,
incorporating compliance with `reuse`.
- Adjusted and enhanced REUSE annotations and configuration to align
with the updated license.
