a11y update in 6.0.x doesn't render accessibility results

[sleblang]

Describe the bug
Received the following console error after updating to version 6.0.12:
withA11y(options) is deprecated, please configure addon-a11y using the addParameter api:

Clicking on the Accessibility Panel in a story at the bottom/side results in the panel stating 'Initializing'

Expected behavior
Accessibility results should be shown

Screenshots

Code snippets
Updated my code in preview.js to accommodate for the new syntax:
addParameters({ a11y: { element: '#root', manual: false }

Thought it might be worth adding a link to the deprecated withA11y decorator bug that I've already raised.

Thanks. I followed this suggestion - #11929 (comment) and it resolved the issue.
