Accessibility: Make sure the Site Health pages have a unique document…

… title.

The document `<title>` gives a name to a web document. In the context of the WordPress admin, a unique, meaningful, title is important for various reasons:
- it allows browser's history to store meaningful entries 
- when multiple browser's tabs are open, it allows users to better identify the tab content 
- it's the first thing screen readers announce when navigating to a web page, thus helping users to identify the nature of the page content
