[Doc] Fix StackedFilters usage examples

[mchaffotte]

Problem

The examples showing how to use do not explain well. They do not use the right prop.

    <List
      filters={
        <StackedFilters config={documentsListFilters} />
      }
    >

It should be:

    <List
      actions={
        <TopToolbar>
          <StackedFilters config={documentsListFilters} />
          <ExportButton />
        </TopToolbar>
      }
    >

Solution

Can you please update the PR description? "The examples are wrong" doesn't explain the problem.
