Fix / Read title while searching (accessibility)

[langemike]

This change causes the screen reader to announce the outcome of your search query while your type, to provide convenience for screen reader users. You could consider this a pragmatic typeahead implementation.

Because aria-live="polite" is used it is announced after you performed a keystroke.

Good to know:

• I also applied aria-liveto the <ErrorPage> so that title is also announced. Adding this also made me realize it can also be beneficial in other cases where ErrorPage get rendered.
• I needed to prevent the announcement of placeholder data while you type. I did that by applying two isFetching-conditions. Though, I think it's more logical to render the placeholder data based on the isFetching-state itself instead of !!query. Something to improve in the future.

This change is based on feedback we got from our internal accessibility auditor. He noted the following:

Visually Impaired Home Screen reader does not automatically announce the typeahead search results. Screen reader should automatically announce the typeahead search results.

I forgot to look at the e2e tests. They should be fixed now
