Expander with checkbox variant changes both text and label

[danielck]

Expected Behavior

When the expanded state of a button changes, the label should not change, because this confuses screen reader users and makes determining the actual functionality hard.

Actual Behavior

The example code for the Expander with checkbox variant has separate text for the unopened and opened states, but also sets the programmatic state using aria-expanded.

Proposed solution

The issue can be worked around by using the same text for both unopened and opened states, but since the component already has a programmatic state, it should probably not have the option at all for more than one label.

Consider setting the label automatically based on the checkbox label.
