[Blueprints] Add dispose functions in afterEach hooks in tests

[mho22]

Motivation for the change, related issues

Based on this comment

The nx run playground-blueprints:"test:vite" command systematically fails due to 10 seconds timeout on the should activate a plugin file located in the plugins directory test.

IIRC I also faced that situation with the PHP.wasm node tests and adding dispose methods made the trick. Let's see if it works here too.

Implementation details

Adding the following portion of code where necessary :

afterEach(async () => {
	php.exit();
	await handler[Symbol.asyncDispose]();
});

Testing Instructions

It looks like it worked!
