[Rename symbol command] Remove unnecessary named import

• VS Code Version: 1.84.2 (1a5daa3a0231a0fbba4f14db7ec463cf99d7768e)
• OS Version: macOS Sonoma 14.1.1

Steps to Reproduce:

1. Create 2 JS files:

// utils.js
export const foo = () => console.log('Hello world!');

// index.js
import { foo as bar } from "./utils.js";

bar();

2. Put your cursor in the word "foo" in utils.js and use the "Rename Symbol" command (F2 by default) to rename the function to bar.
3. Observe the import in index.js has changed to import { bar as bar } from "./utils.js". Since the names import is no longer necessary, the command should instead change the import to import { bar } from "./utils.js".

Reproduce the Rename Symbol command with the two JavaScript files named utils.js and index.js, using F2 to rename foo to bar. Trace the rename flow from that command and verify that the completed import in index.js is import { bar } from "./utils.js" rather than retaining the redundant alias.
