[FR] Use Twitter emojis instead of native ones

[dm-vodopyanov]

Notion uses Twitter emojis, but generated pages use native (for a platform) emojis.

The problem is that on Windows, native Windows emoji are not fully implemented - e.g., Microsoft still did not implement flags in their emojis, so website which uses flags as emojis looks not so good on Windows.

Upd.: Maybe this request suits better for react-notion-x repo. If it is, please let me know, I will create an issue in that repo.

W/a in react-notion-x repo: NotionX/react-notion-x#69.

Is it possible to change emojis here inside only nextjs-notion-starter-kit repo? If not, can this functionality be added to e.g., site.config.ts, or somewhere else?
