In order to solve #1026, we need the ability to associate AST subtrees with individual cell outputs. This is not yet supported with MyST's current AST, so this issue tracks the need to extend our AST in way to handle it.

Note that this is not about formalising the AST change; for now, we can assume that our AST spec is not always up-to-date, and over time reduce that.

Definition of done

• Individual IOutput objects are represented in the AST as individual AST trees
