Dedupe secrets block; consolidate LVGL family paragraph; add docs/README.md

docs/publishing.md's "Repository Secrets" section restated TESTPYPI_API_TOKEN
ownership verbatim from the org-wide runbook now at
dotgithub/docs/publishing-automation.md. Replaced it with a link — the
runbook is canonical and covers all the secrets this repo's release flow
needs (TESTPYPI_API_TOKEN, RELEASE_WORKFLOW_TOKEN).

Replaced the duplicated "LVGL family" positioning paragraph in README.md with
a link to the new canonical section in lvgl-bindings/README.md#the-lvgl-family.

Added docs/README.md — this repo's docs/ dir had no curated index.
