### Summary

User module is not idempotent when update_password: always parameter set in the playbook for macOS 

Result is always showing changed if use already present and no changes in the password . 



### Issue Type

Bug Report

### Component Name

user

### Ansible Version

```console
ansible 2.9.21
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/home/navarihtak/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /home/navarihtak/.local/lib/python3.8/site-packages/ansible
  executable location = /home/navarihtak/.local/bin/ansible
  python version = 3.8.10 (default, Nov 14 2022, 12:59:47) [GCC 9.4.0]
```


### Configuration

```console
# if using a version older than ansible-core 2.12 you should omit the '-t all'
$ ansible-config dump --only-changed -t all
$ ansible-config dump --only-changed
DEFAULT_VAULT_PASSWORD_FILE(env: ANSIBLE_VAULT_PASSWORD_FILE) = /home/navarihtak/.ansible/.vault_pass
HOST_KEY_CHECKING(env: ANSIBLE_HOST_KEY_CHECKING) = False
$
```


### OS / Environment

All MacOS version 

### Steps to Reproduce

```yaml
      - name: Add user for Darwin
        user:
          name: "{{ username }}"
          comment: "{{ username }}"
          shell: "/bin/bash"
          group: "{{ user_group }}"
          password: "{{ user_pass }}"
          update_password: always
          state: present
        when: ansible_os_family == 'Darwin'
        become: yes
```

### Expected Results

It should be idempotent. Result status should shows ok if user is already exist and password is not changed. 

### Actual Results

```console
Always shows result status is changed if user is already exist and password is not changed.
```


### Code of Conduct

- [X] I agree to follow the Ansible Code of Conduct
- Optionally sets the seuser type (user_u) on selinux enabled systems.
        type: str
        version_added: "2.1"
    group:
        description:
            - Optionally sets the user's primary group (takes a group name).
        type: str
    groups:
        description:
            - A list of supplementary groups which the user is also a member of.
            - By default, the user is removed from all other groups. Configure O(append) to modify this.
            - When set to an empty string V(''),
              the user is removed from all groups except the primary group.
            - Before Ansible 2.3, the only input format allowed was a comma separated string.
        type: list
        elements: str
    append:
        description:
            - If V(true), add the user to the groups specified in O(groups).
            - If V(false), user will only be added to the groups specified in O(groups),
              removing them from all other groups.
        type: bool
        default: no
    shell:
        description:
            - Optionally set the user's shell.
            - On macOS, before Ansible 2.5, the default shell for non-system users was V(/usr/bin/false).
              Since Ansible 2.5, the default shell for non-system users on macOS is V(/bin/bash).
            - See notes for details on how other operating systems determine the default shell by
              the underlying tool.
