Improve documentation of signalIL @function
In the last coordinators meeting (2023-05-02) we decided to improve the documentation of the signalIL function enumeration. One point was to add German translations for the signal names in order to improve understanding. After reviewing and improving the documentation in the wiki, it shall be transferred into the EA model. Please notify Milan Wölke for that.
The documentation improvement in the model is to be conducted in a branch off master and published with railML 3.2 maintenance.
