refactor: [#220] remove unused update_environment_ssh_port function

- Removed update_environment_ssh_port() from generate_config.rs - not used anywhere
- Removed function export from black_box module
- Function was originally for bridge networking SSH port updates but never actually used
- All 1395+ tests pass
