[TASK] Postpone the TYPO3 12 compatibility (#639)

We should wait with marking this extension TYPO3-12-compatible
until an installation with TYPO3 12 is actually possible
(i.e., until all development dependencies actually allow this),
as an installation with TYPO3 12 will require changes to the
PHPStan annotations.

Otherwise, we will get PHPStan errors for the first build
after all dependencies allow an installation with TYPO3 12.

This reverts commit 639e414512.
