UI/Let users up&down vote the copilot response

[ah7255703]

• Update dependencies in package.json
• Update API and socket URLs in copilot-widget/index.html
• Add Vote component and implement useVote hook
• add Vote component for users to up/down vote the response
• Add text-blur-out animation to index.css
• add useUp&Down vote impl, and useAsyncFn impl.
• Remove console.log statement in InitialDataContext.tsx
• Refactor Vote component to use async upvote and downvote
• Update API and socket URLs (dummy)
• Refactor Messages and Controller components to use the new Voting Component

We should note that

• this feature is not available on the OSS repo, as it will be less useful (no users).
• so the vote component will be rendered conditionally.
