Update regex in ControllerAclTest

[aleron75]

Description

Change regex in ControllerAclTest::getControllerPath() to avoid classes which are under a namespace with a "Controller" part (like for example controller plugins) being interpreted as controllers causing the Act test to fail.

I need this change because, in the scope of MSI development, I have to define the following plugin for a controller:

    <type name="Magento\Catalog\Controller\Adminhtml\Product\Initialization\StockDataFilter">
        <plugin name="allow_negative_min_qty"
                type="Magento\InventoryCatalog\Plugin\Catalog\Controller\Adminhtml\Product\Initialization\StockDataFilter\AllowNegativeMinQtyPlugin"
                sortOrder="1"/>

The Magento\InventoryCatalog\Plugin\Catalog\Controller\Adminhtml\Product\Initialization\StockDataFilter\AllowNegativeMinQtyPlugin plugin class makes the test fail because it is considered a controller but doesn't extend \Magento\Backend\App\AbstractAction.

Manual testing scenarios

• define a plugin on a controller declaring it under a namespace with a "Controller" part
• run the ControllerAclTest static test
• expect the test to fail
