DeleteButton resource is not passed down

[ybrodsky]

Is your feature request related to a problem? Please describe.
I have a resource named answers and another named questions. Within a route belonging to answers I have a list of questions displayed in a table. I want to use the DeleteButton to be able to delete a question from here. The DeleteButton accepts an attribute resource but it's only used to display the confirmation message.
When the time comes that RA does the actual delete request, it gets the resource from the context, in this case the wrong resource answers. You can see here

react-admin/packages/ra-ui-materialui/src/button/DeleteWithConfirmButton.tsx

Line 53 in 0deb2b5

} = useDeleteWithConfirmController({

where the resource is no longer passed down.

Describe the solution you'd like
To be able to pass resource to the DeleteButton and that property be passed down up until here

react-admin/packages/ra-core/src/controller/button/useDeleteWithConfirmController.tsx

Line 83 in 0deb2b5

const resource = useResourceContext(props);

so that you are able to manually overwrite the context resource.

Describe alternatives you've considered
I managed to resolve my problem using this:

<ResourceContextProvider value="questions">
  <DeleteButton resource="questions" />
</ResourceContextProvider>

but it took me 1 hour of digging through your code, when the instinctively solution is to simply use the resource attribute in the button and have it pass down.
