feat: bump Rsbuild 1.4.0-beta.2 to enhance external module render

[Timeless0911]

Summary

Bump Rsbuild 1.4.0-beta.2.

close: #869

Exciting changes about ESM outputs: no __webpack_exports__ and __WEBPACK_EXTERNAL_MODULE_ now:

Source

import { foo } from "./foo";
import path from "node:path";

console.log(path.join("bar"));

export { foo };

Before

import * as __WEBPACK_EXTERNAL_MODULE__foo_js_fdf5aa2d__ from "./foo.js";
import * as __WEBPACK_EXTERNAL_MODULE_node_path_c5b9b54f__ from "node:path";
console.log(__WEBPACK_EXTERNAL_MODULE_node_path_c5b9b54f__["default"].join("bar"));
var __webpack_exports__foo = __WEBPACK_EXTERNAL_MODULE__foo_js_fdf5aa2d__.foo;
export { __webpack_exports__foo as foo };

Now

import { foo } from "./foo.js";
import external_node_path_default from "node:path";
console.log(external_node_path_default.join("bar"));
export { foo };

For default export, we will continue to enhance the module symbol name in the near future which means external_node_path_default -> node_path.
