TYPO3: 12.4.11

When i try to install the extension via composer i get the following error:

`composer req in2code/femanager
./composer.json has been updated

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require in2code/femanager:*" to figure out if any version is installable, or "composer require in2code/femanager:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.`

Since TYPO3 12.4.10 the core allows Symfony 7 in its dependencies ("symfony/config:^6.4 || ^7.0")
Details: TYPO3-issue 102746.

Currently, femanager has not yet added this compatibility.
