- added condition to YamlFileLoader.php to prevent PHP 8.*

[zloy88]

In TYPO3 11 running on PHP v8.* the YamlFileLoader is throwing constantly a PHP warning, in line 59 because the array key $GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['routes']['additionalPathList'] does not exists initially.

This pull request has been open for over 1 year, is this still being transferred to the main branch?

Is this extension dead?

[Lacr1ma]

@ndurchx Yes, please you something else.

There is a workaround though:
if (!isset($GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['routes']['additionalPathList'])) { $GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['routes']['additionalPathList'] = []; }

Put that into the ext_localconf of e.g. your sitepackage.
