Important: #68079 - Extension “mediace” moved to TER

See Issue #68079

Description

The previously available “mediace” extension has been moved to the TYPO3 Extension Repository (TER) and will be managed on GitHub (https://github.com/FriendsOfTYPO3/mediace).

An upgrade wizard in the Install Tool will check if the extension is needed. If so, it is downloaded from the TER and installed if necessary.
