No default account in users.json

[thecasualtrex]

Hello I recently just installed Samba-Manager and after getting around the issue-18 with python the default credentials admin / admin were not working. After digging through the commit history I saw that the user for admin in [users.json](https://github.com/lyarinet/Samba-Manager/blob/main/users.json) was removed. Adding it back allowed me to login again.

you did not read install instructions,did you :)
it is pretty well hidden in plain sight(don't ask how i know) on main page
it is /register

Ah sorry about that, I ran the quick setup script and was reading the instructions that still say the default login is admin / admin in the console. It might be helpful to update the console script and move the 'After Install' instructions closer to the actual 'install' instructions as well so prevent any confusion since its under the uninstall instructions :)
