chore: update Twitter link and labels to X branding (#1233)

1. Changed `href` in GetConnectedButton from Twitter to X URL (https://x.com/base)
2. Updated `title` and `aria-label` to reflect "Join us on X" instead of "Join us on Twitter"
3. Kept `iconName` and `eventName` as "twitter" to ensure compatibility with existing icons and events
