Description

Current behaviour

Currently we do license headers as follows:

/*

 * Copyright (c) 2022,2024 Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V. (represented by Fraunhofer ISST)

Expected behavior

After update of Eclipse Foundation committer handbook / TRG 7.02, we should only use the year of the initial commit and no further days. Making the above to the following.
