TYPO3 11 LTS available
Mask (and 105 further Extensions) are compatible with TYPO3 11 LTS.
Steps to reproduce
Open https://extensions.typo3.org/ and have a look to the Box "Works with TYPO3" on the left side. And have a look at: https://extensions.typo3.org/extension/mask -> "This version supports TYPO3 10LTS 11LTS"
What is the expected correct behavior?
The TYPO3 Website should not show compatibilities with future TYPO3 versions. Also, when this is an error in ext_emconf or composer.json.
