Playground: code formmating broken with TS3.4+ readonly notation

Code:
Looks like the readonly modifier for arrays breaks code reformatting in the Playground.

// comment out to allow reformatting
const oops: readonly number[] = [1, 2, 3];
/*
SyntaxError: "',' expected. (2:22), parser-typescript.js
> 2 | const oops: readonly number[] = [1, 2, 3];
    |                      ^
*/

// Alt + Shift + F: IT DOES NOTHING!!!
const 
x 
= 
1;

Expected behavior:
Code reformats (so const x = 1; is moved to a single line)

Actual behavior:
Code does not reformat. A console error indicates that the readonly modifier is not expected.

Weird, looks like the prettier playground doesn't have this problem.

The new playground will go back to the built-in TS formatter, so you're welcome to look at maybe updating the prettier for this playground in the meantime.

Moving back to the TS formatter fixed this 👍

Playground link still looks bad to me; so does staging... is there some website/playground release schedule or some other thing I'm missing?

It's on this PR: #76
