docs: fix HTML report links to use GitHub HTML preview service

GitHub doesn't render HTML files directly in the browser - it shows the
raw source code. Fix this by using htmlpreview.github.io service which
properly renders HTML files from GitHub repositories.

This allows users to actually view the interactive benchmark reports
instead of seeing raw HTML code.
