Motivation for the change, related issues

Based on this issue.

Related to this function.

It looks like the ICU data is not found when running the below Blueprint. Even if the file is located in /internal/shared before running the playground.run(...) in run-php.ts.

Implementation details

• Added a new Intl classes should work when intl is enabled test in playground/website/playwright/e2e/blueprints.spec.ts

Blueprint

{
	"features": {
		"intl": true
	},
	"steps": [
		{
			"step": "runPHP",
			"code": "<?php \n\n$data = array(\n    'F' => 'Foo',\n    'Br' => 'Bar',\n    'Bz' => 'Bz',\n);\n\n$collator = new Collator('en_US');\n$collator->asort($data, Collator::SORT_STRING);\n\nthrow new Exception( json_encode($data, JSON_PRETTY_PRINT ) );"
		}
	]
}

Should throw :

Uncaught Exception: {
    "Br": "Bar",
    "Bz": "Bz",
    "F": "Foo"
} 

But throws :

Uncaught IntlException: Constructor failed
