Translations for notifications dialog

[chris48s]

At the moment, we aren't translating the button text on the notifications dialog:

WhereDoIVote-Widget/src/Notifications.js

Lines 22 to 30 in 2f345ca

	<a
	className="dc-btn-secondary"
	target="_blank"
	rel="noopener noreferrer"
	title={'Read more information about this ' + props.title}
	href={props.url}
	>
	Read More
	</a>

This sort of doesn't matter in that the rest of the text in the dialog ( props.detail and props.title ) comes from the API and we won't have translations for that either, so if all the other text in the dialog is in English regardless of the user's language preference its not a massive issue that the button is too.

Need to think about how to deal with this situation..
