fix: Remove COPR repositories and use EPEL packages

- Remove kvanderr COPR repositories (internal/subscription-only)
- Rely on EPEL packages for opentelemetry-cpp and dependencies
- Simplified Dockerfile setup by removing COPR configuration
- EPEL should provide the necessary packages for public CI builds
