Translate time zone label according to current locale in Stores > Configuration > Advanced Reporting

[adrian-martinez-interactiv4]

Time zone label gets translated according to operating system settings, instead of using current locale:

This even can make some functional tests fail, when executed on machines with different locale options, see \Magento\Analytics\Test\Constraint\AssertConfigAnalyticsSendingTimeAndZone::processAssert:

        \PHPUnit_Framework_Assert::assertEquals(
            'Eastern European Standard Time (Europe/Kiev)',
            $configAnalytics->getAnalyticsForm()->getTimeZone()
        );

Description

Adapt \Magento\Analytics\Block\Adminhtml\System\Config\CollectionTimeLabel::render method to use current locale to render time zone label, as done in \Magento\Framework\Locale\TranslatedLists::getOptionTimezones

Fixed Issues (if relevant)

1. None AFAIK

Manual testing scenarios

1. Change current admin user interface locale to something different of English (United States), like Spanish (Spain)
2. In section Stores > Configuration > Advanced Reporting, you should see translated comment according to current locale.
