Improve password prompt wording in createsuperuser management command

[Ketan Sahu]

When running python manage.py createsuperuser, the password prompt currently shows:
`
Password:
`
Nothing is printed while typing (for security), but many beginners might think the terminal has frozen or the command isn’t working, since there’s no hint that the input is hidden.

Suggestion:
Update the password prompt in the createsuperuser management command to something clearer, like:
`
Password (input hidden):
`
or
`
Password: [input hidden]
`

Benefit:

• Makes clear that password input is working as intended, which is especially helpful for new users or beginners.
• Prevents confusion that the terminal/command has frozen.
• Brings Django’s CLI user experience in line with user-friendly conventions.
