being able to send spoiler text from cinny

Describe the solution you'd like

||text|| -> plain (Spoiler: text) or something, html <span data-mx-spoiler>text</span>

Describe alternatives you've considered

text - ew verbose

text - ew still verbose, and has no grounds in matrix #### Additional context discord uses || afaik element has no way to create it besides a command (for the whole message) not part of commonmark so custom parsing is probably needed

afaik element has no way to create it besides custom events

No in-line spoilers, but full-message with /spoiler the spoiler text works in Element.
