Fix calculateColor function declaration in browser-extension

[Copilot]

The calculateColor function was assigned to an implicit global variable instead of using a proper declaration keyword, causing potential hoisting issues and strict mode violations.

Changes

• Added const keyword to calculateColor function declaration in 5-browser-extension/solution/src/index.js
• Rebuilt webpack bundle to reflect the change

// Before
calculateColor = async (value) => {
  // ...
};

// After
const calculateColor = async (value) => {
  // ...
};

Fixes microsoft#1547
