Evaluate which translation strings are still used

[moorscode]

The strings/translations in the following location need to be checked, because most of them are not used anymore and are translated in yoast-components.

wordpress-seo/admin/formatter/class-metabox-formatter.php

Line 156 in 943631a

private function get_content_analysis_component_translations() {

Because these are slightly different, they appear as different strings in translate.wordpress.org, thus will take time to get translated.

These can all be simply removed because we now parse the JavaScript for strings that need to be translated instead of duplicating the strings in PHP.
