This adds an empty state for blueprint table when there are no blueprints created.
Changes are gated behind experimental flag and preview so that the original ImagesTable isn't affected.
The data-testid for the Create image button in the empty state has been
renamed from create-image-action has been renamed to create-image-action-empty-state.
The test `renders EmptyState child component` started failing after changing
isBeta() from false to true in the useChrome() mocking function.
It was failing because the findBy query selector was able to find two
components with this data-testid, which was truly the case - the Create
Image button in the table header, and the Create Image button in the
empty state.
I have no explanation for why this test wasn't failing before.
