We render a new Spoiler component for text content parsed to be
spoilers. Upon tap, this Spoiler component reveals the text beneath
(https://linear.app/comm/issue/ENG-2011/display-the-spoiler-content-on-tap-within-messagelist-[native]).
This diff will not be landed until ENG-2072 is addressed, to resolve the
spoiler state not being remembered upon message tap.
