Superusers can't change users passwords

[stuartc]

As a superuser, when editing user records the form has a "password" input for overriding/resetting users passwords.

However the value is never saved.

I have reproduced this locally on main:

• Yes
• No

To Reproduce Steps to reproduce the behavior:

1. Go to 'Admin Menu'
2. Click on 'Users'
3. Scroll down to a specific user and click 'Edit'
4. Enter in a valid password
5. Click Save

Expected behaviour

While there is a flash message saying the user has been updated, this is not the case.
