fix: swap content/data keys in onProductOptionsChanged event detail

[sacr3dc0w]

What?

Fixes a bug in productOptionsChanged where the content and data keys in the onProductOptionsChanged CustomEvent detail payload were swapped.

Before:

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

After:

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

productAttributesData is the structured data object returned from the optionChange API response, and should be keyed as data. productAttributesContent is the rendered template string, and should be keyed as content. Any listeners on onProductOptionsChanged expecting conventional key semantics would have received the wrong value.

Requirements

• CHANGELOG.md entry added (required for code changes only)

Tickets / Documentation

• Swapped data/content values in onProductOptionsChanged event detail #2541

Screenshots (if appropriate)

N/A — logic fix with no visual output.
