- Remove unnecessary build argument
- Upgrade `luarocks` version to `3.11.0`
- Add build steps for `ngx_brotli`
- Remove `lua-suffix` from luajit configuration
- Update `LUA_PATH` environment variable
- Remove unused `ngx_brotli` build steps
- Remove unnecessary cleanup steps
- Remove unused `RESTY_OPENSSL_URL_BASE` build argument
- Remove unused files after compilation
