Move local-jekyll.md out of docs/site/ to docs/

local-jekyll.md is dev onboarding for previewing the docs site, not
site content itself. Jekyll's Liquid engine tries to parse the literal
'{% include %}' examples in the file (even inside backticks) and fails
with 'Invalid syntax for include tag'. Jekyll 3 (used by GitHub Pages)
has no per-file render_with_liquid escape.

Moving the file to docs/local-jekyll.md keeps it discoverable next to
the site it documents, but outside the Jekyll source tree so it's
never processed.
