Studio: Update php-wasm ( playground dependecies)

[kozer]

Fixes https://github.com/Automattic/dotcom-forge/issues/8867

Proposed Changes

This PR updates the following packages to the latest version:

• @php-wasm/node
• @php-wasm/universal
• @php-wasm/scopes
• @wp-playground/blueprints

During the update we ran into various issues, some of which required changes in the wordpress-playground repository:

• Fix issue with types definitions that were missing
• Fix issue with websocket proxy server not closing when a phpruntime is exited.

We had to change a couple of things in the current implementation of wp-now within Studio as it was relying on outdated APIs. These changes mainly relate to how we obtain a PHP instance.

Testing Instructions

• Try running the app on MacOS and Windows
• We should ideally systematically go over the list of smoke tests to ensure that this update did not break anything that was previously working.

Pre-merge Checklist

• [ ] Have you checked for TypeScript, React or other console errors?

I smoke tested the app with the build from this branch and everything worked as expected. The only thing that I noticed is that this branch is about 20 - 30 seconds slower for me when importing a database. Steps to reproduce:

• Export a database from a Studio site
• Import a database into the same Studio site
• Comparing it to the trunk, the trunk looks faster by about 20 seconds. The import / export does complete successfully though
