clarification regarding exhibition settings

[tnier01]

With regard to the settings to be set, it is described that all settings can also be subsequently edited in config.yaml (see text field under "Configuration of the station"). However, this statement is not valid for the extra exhibition settings, so the text field contains incorrect information. There should therefore be an extra paragraph for the exhibition settings and a corresponding explanation that these can currently only be changed on the server side or when the station is created for the first time.

• adapt text field which explains that some and which settings can be also changed later on, on the station
• create new paragraph for the exhibition settings
• create text field which explains, that exhibition settings are currently only adjustable during creating the station or via server settings by the project team/admins
