Display the AST even with syntax errors (#11147)

Browse source 
## Summary

This PR updates the playground to display the AST even if it contains a
syntax error. This could be useful for development and also to give a
quick preview of what error recovery looks like.

Note that not all recovery is correct but this allows us to iterate
quickly on what can be improved.

## Test Plan

Build the playground locally and test it.
