[Android] Shift Dates (PLS) Design Changes

[moiz994]

As per new design guidelines we need to update the Shift Due Dates (PLS) experience.

The proposed design, attached and viewable in Figma. When the user shifts due dates from within the Course tab, the dialog should include the button to View All Dates. When the user shifts due dates from within the CTA inside the Dates tab, the dialog should not include a View All Dates button.

Also want to make sure to note the wider dialog, which helps to distinguish this snack bar view from the content underneath.

With View All Dates, for within the Course tab

Without View All Dates, for within the Dates tab
