➕(frontend) add emoji-mart packages

We need functionalities and data to implement a custom emoji picker
component, as blocknote's emojipicker component triggers and uses cases
are limited.
add to package.json the following packages:
- "emoji-mart": provides functions and components for
displaying, searching and selecting emojis.
- @emoji-mart-data: offers pre-configured sets of emojis.
- @emoji-mart/react: React Picker component
