xsl: Drop the xmlns=xhtml attribute from all stylesheet elements

This caused some HTML elements to contain spurious xmlns attributes,
e.g. in quickstart/index.html:
<span xmlns="http://www.w3.org/1999/xhtml" class="Statement">dodoc</span>

Apparently this is valid in HTML 5, so neither tidy nor the W3C
validator would warn about it (and it went unnoticed since 2015):

"In HTML documents, elements in the HTML namespace may have an xmlns
attribute specified, if, and only if, it has the exact value
'http://www.w3.org/1999/xhtml'."
https://html.spec.whatwg.org/multipage/dom.html#global-attributes

Use single and double quotes consistently. Whitespace fixes.
