Change the naming of the `Lernbereiche verwalten` and make it easy to find

[lunars97]

Is your feature request related to a problem? Please describe. Right now the Lernbereiche verwalten is located on the sidebar when we click on three dots. It can be difficult for users to find this sidebar and the naming of Lernbereiche verwalten is not easy German for people who are learning German.

Describe the solution you'd like

• It would be great to change the formulation of the Lernbereiche verwalten to Berufswortschatze suchen or Berufswortschatze auswählen or something like these.
• It would be great to put the button on the home page which leads directly to the list of occupations.
