[BUG] namecheap module: Passed invalid arguments to namecheap_<module>.<function>: must be str, not NoneType

[ggiesen]

Description
When using any of the namecheap execution modules, I receive the following error:

Passed invalid arguments to namecheap_<module>.<function>: must be str, not NoneType

Example with namecheap_users.check_balances:

[WARNING ] Passed invalid arguments to namecheap_users.check_balances: 'NoneType' object is not subscriptable

    Checks if the provided minimum value is present in the user's account.

    Returns a boolean. Returns ``False`` if the user's account balance is less
    than the provided minimum or ``True`` if greater than the minimum.

    minimum : 100
        The value to check

    CLI Example:

    .. code-block:: bash

        salt 'my-minion' namecheap_users.check_balances
        salt 'my-minion' namecheap_users.check_balances minimum=150

It looks like the __salt__ dunder is set to None in utils/namecheap.py (and not subsequently set), and as such it can't read the config.

Setup
/etc/salt/minion.d/namecheap.conf:

namecheap.name: cheapuser
namecheap.key: aid3ofietaizie0quaeNgutheY8uzeim
namecheap.client_ip: 192.0.2.1
namecheap.url: https://api.namecheap.com/xml.response

Please be as specific as possible and give set-up details.

• VM (Virtualbox, KVM, etc. please specify)

AlmaLinux 8 VM on VMware vSphere 7.0. Minion is running on same host as master.

Steps to Reproduce the behavior

1. $ salt minion namecheap_users.check_balances

Expected behavior
Return whether the account balance exceeds $100
