PHP 7.1 syntax for array destructuring doesn't work on PHP 7.0

[OldStarchy]

Description

The new syntax for array destructuring is used here

commerce/src/controllers/OrdersController.php

Line 332 in 7ae6334

[$field, $direction] = explode('|', $sort);

However this requires PHP >= 7.1 and is an unexpected breaking change. I guess this was an unintentional change due to php-cs-fixer based on the commit message 9a8c556

Fix usage for htmlspecialchars

The minimum required version of PHP should be specified in the composer.json so we don't accidentally install an incompatible version.

Steps to reproduce

1. Install craft commerce 3.0.5 on a PHP 7.0 server
2. Navigate to the commerce tab in the CP

Additional info

• Craft version: 3.4.2
• PHP version: 7.0.33
• Database driver & version: N/A
• Plugins & versions: Commerce 3.0.5

This happens in all versions >= 3
