Doc Bug - Admin UI viewing requires both "Superuser" and "Staff".

[scetron]

Environment

• Nautobot version (Docker tag too if applicable): 1.4.2
• Python version: 3.8
• Database platform, version: postgres
• Middleware(s):

Steps to Reproduce

1. Add a user with super user permission only.
2. Login with user.
3. Attempt to view admin GUI.

Expected Behavior

Per the documentation, I expected to see the admin GUI.

Observed Behavior

I did not see the admin GUI.

I was able to add the staff permission to the user, and the user is now able to see the admin GUI.

This issue is for amending the documentation to mention that both Superuser and Staff is required to view the admin gui.
