Update the built-in HTML sample snippet to follow current web standards
and reduce unnecessary boilerplate:
- Add lang attribute to <html> tag as first tab stop (W3C recommended)
- Remove outdated IE compatibility meta tag (IE is no longer supported)
- Remove unnecessary type='text/css' and media='screen' from <link>
(default values in HTML5)
- Remove <script> tag (modern templates often handle scripts differently)
- Move viewport meta before title (following common convention)
