Prevent 'undefined array key' warnings with php 8 when extconf 'allowedDoktypes' missing #476

Closed rengaw83 closed 2 years ago

In TYPO11 with PHP 8 there are a PHP Warning: Undefined array key .... This PR adds a additional check (null coalescing operator's) to prevents this error.

I'm not sure how this error would occur since allowedDoktypes should always be set through the default configuration: https://github.com/Yoast/Yoast-SEO-for-TYPO3/blob/master/ext_localconf.php#L85-L88

But an extra check for this is never bad, so I'll merge it. Thanks for the PR!
