Describe the bug

try to upload media in wordpress running in node

Expected behavior

the media is uploaded and copied to wp-content/uploads

Actual behavior

fileInfos and addUploadedFile that were in @php-wasm/node 0.5.6 are not there anymore. I tried to use the $_FILES superglobal and then run php.request:

           const uploadedFile = data.files["async-upload"];
            // {
            //   key: "async-upload",
            //   name: "Yin_yang.png",
            //   size: 27700,
            //   type: "image/png",
            //   arrayBuffer: new Uint8Array([137, 80, ])
            // }
            const ext = path.extname(uploadedFile.name);
            const vfsPath = `temp-${crypto.randomBytes(6).readUIntLE(0, 6)}${ext}`;
            ;

            // 1. Write the actual data to the Wasm VFS
            await php.writeFile(vfsPath, uploadedFile.arrayBuffer);

            // 2. Mock the $_FILES superglobal
            // This script runs BEFORE your target script
            await php.run({
                code: `<?php
            $_FILES['async-upload'] = [
                'name'     => '${uploadedFile.name}',
                'type'     => '${uploadedFile.type}',
                'tmp_name' => '${vfsPath}',
                'error'    => 0,
                'size'     => ${uploadedFile.size},
            ];
        ?>`

            });

it fails in php here

	// A properly uploaded file will pass this test. There should be no reason to override this one.
	$test_uploaded_file = 'wp_handle_upload' === $action ? is_uploaded_file( $file['tmp_name'] ) : @is_readable( $file['tmp_name'] );
	if ( ! $test_uploaded_file ) {
		return call_user_func_array( $upload_error_handler, array( &$file, __( 'Specified file failed upload test.' ) ) );
	}

Steps to reproduce
