Add a Reset Password button under Security > List Users > Edit user

### Description

Currently the way to reset the password via the UI is to go to Security > List Users > Show record (loupe icon) > Show User > Reset Password

I think it's counterintuitive that the reset password button is only there, and not in under the Edit record > Edit User

So I believe it would be better if the reset password button is show in both Show User and Edit User.

### Use case/motivation

It will be more intuitive. At least for in my case I couldn't find until I was told in https://github.com/apache/airflow/issues/37009#issuecomment-1912062010 that that button exist.

The "reset password" button itself is not very well documented, at least the google query `site:airflow.apache.org "reset password"` does not find any reference to it.

Hopefully a more prominent place in the UI will reduce some of the confusion. I also tried to document "reset password" in stackoverflow at least https://stackoverflow.com/a/77886646/90580

Start with the Security > List Users > Show User > Reset Password flow and compare it with the Edit user screen. Expose the existing reset-password action in Edit User while keeping it in Show User; done when both screens offer the action with the same expected behavior.
