Notification regarding version of documentation cannot be dismissed

[rjgotten]

The notification alerting the end-user they're looking at the Webpack v5 documentation rather than the v4 documentation cannot be dismissed. There's no explicit button to dismiss it. It keeps reappearing on every page.
It actually blocks essential parts of the pages.

[EDIT]
A close button is rendered on Chrome.
NOT on Firefox.

(Also <div role="button"> is not an actual button.)

Hi @rjgotten can you assign this to me. I would like to work on it by hiding it with custom CSS

Let's remove notifier at all, webpack@4 outdated

@alexander-akait Can you please assign this to me? I’d really like to work on its implementation.

Send a PR to remove the banner, no need to assign anyone here. First serve, first merge
