Add Maestro test for Image.getSize with local drawable resources (#56945)

Summary:

Adds a Maestro E2E test that exercises the new RNTester example for `Image.getSize()` with Android drawable resources. The test navigates to the Image examples, opens the "Image.getSize with local drawables" example, taps the run button, and verifies that VectorDrawable and PNG drawable dimensions are returned correctly in dp, and that the error case for a nonexistent drawable shows an error message.
