Colada loader: refetch vs reload

[JarvisH]

In the Colada loader, I am struggling to see the difference between the returned functions reload and refetch.
The examples also add to the confusion like fx:

<button @click="reload()">Refetch</button>

They are almost the same. I added more info at e7789e9.
reload is the method that is required by the Data Loaders spec while refresh and refetch are specific to Pinia Colada. So Colada loaders have both to comply with both APIs.
