Rename example to "Envoy TCP Routing"

Rename tcp_rerouting to envoy_tcp_routing to:
- Clearly indicate this is an Envoy-specific example
- Use "routing" instead of "rerouting" for better terminology

Changes:
- Renamed directory: examples/tcp_rerouting → examples/envoy_tcp_routing
- Updated package name: proxy-wasm-example-envoy-tcp-routing
- Updated all references in README.md files
- Updated Docker Compose network name and WASM filename
- Updated Envoy config filter names and WASM path
- Updated .gitignore path
