TYPO3 Core

Describe the bug
If a Content Blocks Collection is using tt_content as a foreign_field and for example a typo3 form is added in this. The $LANG variable is not available in this scope and we get an Exception:
PHP Warning: Undefined global variable $LANG in /html/typo3-composer/vendor/typo3/cms-form/Classes/Domain/Configuration/FlexformConfiguration/Processors/FinisherOptionGenerator.php line 96

To Reproduce
Steps to reproduce the behavior:

Create an Element that uses a Collection with foreign_table: tt_content
Insert a Typo3 Form element into it
Open frontend and get the error
Expected behavior
The Form element gets the $LANG variable in this scope.
