ci: remove the Docs Deploy (GitHub Pages) workflow

GitHub Pages was never enabled in this fork's repo settings, and the
workflow's own comment ties it to docs.sanaei.dev, upstream's custom
domain, not something this fork has. Failed both times it ever ran
(including once before today, unrelated to any of this session's
other changes) with "Ensure GitHub Pages has been enabled". Docs CI
(docs-ci.yml, lint/build-check only, no deploy) is untouched.
