shr_product_grid_fragment.xml changes in MDC-104 without explanation

[ragraham91]

Describe the bug
In page 3 of MDC-104, we are told to add this code:

<LinearLayout
   style="@style/Widget.Shrine.Backdrop"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:gravity="center_horizontal"
   android:orientation="vertical"
   android:paddingTop="100dp"
   android:paddingBottom="100dp">

</LinearLayout>

Note paddingTop and paddingBottom of 100dp.

Further down the page, this has become:

<LinearLayout
   style="@style/Widget.Shrine.Backdrop"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:gravity="center_horizontal"
   android:orientation="vertical"
   android:paddingTop="88dp">

   <include layout="@layout/shr_backdrop" />
</LinearLayout>

Note paddingTop of 88dp and no paddingBottom. The change is not mentioned in the tutorial text.

Expected behavior
Mention that the paddings need to be changed.
