docs(PPDSC-2268): Accordion documentation

[Srinivasan-Ramasamy]

PPDSC-2268

What

1. Accordion doc page UI - http://ncu-newskit-docs.s3-website-eu-west-1.amazonaws.com/ppdsc-2268-accordion-page/components/accordion/
2. Fix for SEO Considerations section extra space at the bottom in all the doc pages.

I have done:

• Written unit tests against changes
• Written functional tests against the component and/or NewsKit site
• Updated relevant documentation

I have tested manually:

• The feature's functionality is working as expected on Chrome, Firefox, Safari and Edge
• The screen reader reads and flows through the elements as expected.
• There are no new errors in the browser console coming from this PR.
• When visual test is not added, it renders correctly on different browsers and mobile viewports (Safari, Firefox, small mobile viewport, tablet)
• The Playground feature is working as expected

Before:

After:

Thanks @baburay23 and @mutebg for taking the time to review 👍

[mutebg]

can you use
<UnorderedList overrides={{ paddingBlockStart: 'something', paddingBlockEnd: 'space050'}}>
instead of that block and <br />

Thanks @mutebg for the review and suggestion and It's really helps on before and after elements spaces. 💯

Changes are done.
