docs: allow inline literals in paragraphs to wrap to prevent overflow

Browse Source 
Some documentation pages contain long inline literals in paragraph
text that can force page-wide horizontal scroll overflow and break
layout on smaller screens.

Override the default `span.pre` white-space behavior for inline
literals and use `overflow-wrap: anywhere` so they can wrap when
needed. For code used as part of a paragraph, wrapping is appropriate
because it is stylistically part of the surrounding text. Code blocks,
by contrast, are meant to preserve formatting fidelity and are better
served by contained horizontal scrolling.
