BUG/MINOR: stats: add lang attribute to html tag

Browse Source 
The "html" element of the stats page was missing a "lang" attribute.
This change specifies the "en" value, which corresponds to english
language.

It is also a required element for WCAG Success Criterion 3.1.1, which
renders the web more accessible through a set of requirements. In this
case it allows assistive technologies such as screen readers to
determine the language of the page.

HTML standard: https://html.spec.whatwg.org/multipage/dom.html#attr-lang
