[QA] explain how to properly create a space

[jnweiger]

Seen in 7.0.0-rc.2

As use Alice, click on 'Spaces' in the left sidebar. An empty screen with "Learn about spaces (?)" appears. the question mark has this text:

Spaces are special folders for making files accessible to a team.
Spaces belong to a team and not to a single person. Even if members are removed, the files remain in the Space so that the team can continue to work on the files.
Members with the Manager role can add or remove other members from the Space.
A Space can have multiple Managers. Each Space has at least one Manager.

I'd suggest to add a hint here, how Alice should proceed to get her first space.

Probably Alice requests admin to help with space creation. Admin most likely goes to Admin-Settings -> Spaces

Nothing there, just an empty page.

Instead, user admin needs to go to `Files -> Spaces' and first create a space for himself, then add Alice as Manager, and remove himself.

Alternatively, user admin may find that promoting Alice to role 'Space Admin' solves the request more efficiently. Now Alice can create spaces herself. From a seurity perspective, this is a tempting, but dubious approach. Besides creating her own spaces, Alice can now also see and delete all spaces in the system.

Is user admin able to create spaces due to a hidden permission, that is not exposed in the web UI?
