Custom shipping methods show a zero price

[lukeholder]

When viewing custom shipping method options, the price value is shown as zero.

Related to this, I can't seem to call method.getShippingRules() from my custom shipping methods in verbb/postie#36

{% for handle, method in cart.availableShippingMethodOptions %}
    {{ dump(method.getShippingRules()) }}
{% endfor %}

See https://d.pr/i/Tb3xni which is correct for Commerce shipping methods, but not for a shipping method provided by Postie.

Looks like this issue might be back in 3.4.x.

Here, I'm outputting the available methods with Order::getAvailableShippingMethods() (deprecated) and Order::getAvailableShippingMethodOptions() with only the former approach working correctly.

<h2>availableShippingMethods</h2><br>
    {% for handle, method in cart.availableShippingMethods %}
        {% set price = method.priceForOrder(cart)|commerceCurrency(cart.currency) %}
        
        {{ method.name }} - {{ price }}<br>
    {% endfor %}

    <h2>getAvailableShippingMethodOptions</h2><br>
    {% for handle, method in cart.getAvailableShippingMethodOptions %}
        {% set price = method.priceForOrder(cart)|commerceCurrency(cart.currency) %}
        
        {{ method.name }} - {{ price }}<br>
    {% endfor %}

    <br><br>

The top 3 are Commerce-created methods, the others are Postie-provided ones.

Believe this is fixed. If it isn't please raise a new issue with steps to reproduce. Thanks.
