Swapped data/content values in onProductOptionsChanged event detail

[jorgespace]

The onProductOptionsChanged event dispatched in the productOptionsChanged method currently has its data and content properties swapped, which contradicts the original intent of PR #2400.

detail: {
    content: productAttributesData,
    data: productAttributesContent,
}

The correct assignment should be:

detail: {
    content: productAttributesContent, 
    data: productAttributesData,
}

Impact:
This could affect any code listening to the onProductOptionsChanged event that expects the correct data in each property.

Suggested Fix:
Simple swap of the values in the event detail object to match their semantic meaning.
