test: Add visual regression coverage for borderless table inside container with paddings

[jperals]

Description

Borderless table in Visual Refresh does not include its own internal paddings so the padding needs to be provided by the container, whereas in Classic the padding from the container needs to be removed.

We have visual regression test for a borderless table inside a container with disableContentPaddings={true}, which is how it is supposed to be used in Classic, but not inside a container with disableContentPaddings={false} (or without disableContentPaddings set), which is how it is supposed to be used in Visual Refresh.

How has this been tested?
