[Feature request] collapsed callouts render the actual collapsing

[Vassago-rw]

Is your feature request related to a problem? Please describe.
Since I am trying to use noteshare to share reading notes with my friends, sometimes I want to fold up part of the content that may involve spoilers, so I am hoping that callouts can have actul collapsing.

Describe the solution you'd like
make callouts that have the "+" or "-" in them render like foldable callouts rendered natively in obsidian.
