ariaLiveSRPane is not being removed from the DOM

[mark-hingston]

Describe the bug
The #ariaLiveSRPane doesn't seem to be removed from the DOM when the drop-in component is unmounted.

To Reproduce
Steps to reproduce the behavior:

1. Complete a payment using Adyen drop-in
2. The #ariaLiveSRPane container remains on the page after the Adyen drop-in component is unmounted.

<div class="sr-panel-holder" id="ariaLiveSRPanel"><div class="adyen-checkout-sr-panel--sr-only" role="log" aria-relevant="additions text" aria-live="polite" aria-atomic="true"><div class="adyen-checkout-sr-panel__msg">Payment Successful</div></div></div>

Expected behavior
The #ariaLiveSRPanel should be removed when the component is unmounted.

Additional context
@adyen/adyen-web: 6.0.2

@mark-hingston - the ariaLiveSRPanel is a checkout level module and, as such, is not dependent on the presence, or not, of any component level entities (like Dropin, or a specific paymentMethod related component).

Thus it sits free from any component's mount/unmount process.

What trouble is its continued presence in the DOM causing?
