docs: document global entry behavior in EntryPlugin

[Copilot]

Documents the behavior change from #12096 where global entries (entries with name: undefined) are now injected into async entrypoints (Web Workers) in addition to regular entrypoints.

Changes

Added documentation to website/docs/en/plugins/webpack/entry-plugin.mdx and website/docs/zh/plugins/webpack/entry-plugin.mdx:

• Global Entry section: Explains that name: undefined creates a global entry whose dependencies are injected into both regular and async entrypoints
• Use cases: webpack-dev-server HMR runtime, ModuleFederationPlugin initialization, custom plugins requiring cross-context availability
• Example: Demonstrates global entry creation and injection behavior

// Global entries are now available in Workers
new rspack.EntryPlugin(
  context,
  './global-runtime.js',
  { name: undefined }
);

// This entry will be injected into:
// - Regular entry chunks
// - Worker entry chunks created with new Worker()

This ensures users understand that global dependencies now work correctly in Web Worker contexts.

Original prompt

submit a PR to document the new behavior in #12096, adding docs to:

website/docs/en/plugins/webpack/entry-plugin.mdx
website/docs/zh/plugins/webpack/entry-plugin.mdx
