How to disable workspaces?

Nextcloud 18 introduced the so-called workspaces. This shows a readme file on top of any folder in Nextcloud which will be disturbing for most users, so you should disable them if you have no usecase for them.

1. Run over CLI:

   sudo bash /var/scripts/menu.sh
2. Choose Nextcloud Configuration -> Disable workspaces
3. Choose to disable rich workspaces

Rich workspaces are now disabled.
