chore: update rspack 1.6.5 (#86853)
update @next/rspack-core version to 1.0.2 and update the snapshot
other changes:
- packages/next/src/build/webpack-config.ts
Adjusted configuration to account for differences in default node config
between Rspack and Webpack.
- packages/next/src/shared/lib/format-webpack-messages.ts
Added a fallback to moduleIdentifier in cases where Rspack does not
correctly populate moduleName.
