Instead of using `unified_reactions` mapping start using `name_to_codepoint` mapping for converting emoji name to codepoints. We were using `unified_reactions` mapping because prior to emoji web PR `name_to_codepoint` mapping was generated using emoji_map.json which contained old codepoints but for reactions new codepoints were required to display them using sprite sheets.
