Clean-up attributes in email-link

`app-c-email-link` is used on a block-level element (in our case a div) so there's no need to declare it again with `display: block`

this application doesn't use colour compatibility mode (has in turned of  `$govuk-use-legacy-palette: false;` in `application.js` as we now use the new colour scheme across the app), hence no need to declare the legacy colours anymore.
