Melange playground

[davesnx]

Since Melange released a new playground we could integrate it with the current ReasonML website, either with a redirect or embed it directly.

JavaScript and Native compilations are topics that are spreaded across the website, and it's a must fix. Either of the solution we choose, would be nice to have it clear for users to understand Reason + Melange -> JS, Reason + dune -> native.

This issue will be used as an umbrella for all issues related with current Playground:

• Missing files for setupSomeArtifacts.js? #366
• Type errors not visible on reason/try #359
• Try https://microsoft.github.io/monaco-editor/ for Try playground #106
• [Try] endless crashing loop #661
• Inline records do not work on the playground #607
• Try page crashing, can't recover #544
• A valid snippet crash the playground type x = A{x: int}; #604
• URL always crash on reasonml.github.io reason#2576

Preferred solution would be to showcase both playgrounds: sketch.sh and melange.re as a page.

and remove/deprecated the current playground/refmt.js

I just tried in the melange playground all the referred issues that were crashing in the reason playground, and all seem to work fine now:

Issue	Code	Melange playground link
#604	type x = A{x: int};	Link
#607	type t = | Hi({name: string});	Link
#544	Js.log(0x lxor 0x80000000);Js.log(19 lxor 0x40000000);	Link
#661	let a : int = 1s;	Link

Maybe we can close those with a note directly?

Once we fix this issue, totally!
