Subject: [PATCH] ci: run docs-fix via Docker and track its Node version with
 Dependabot

- docs-fix.yml: drop runner-native setup-node@18 / setup-python / 'yarn install'
  (redundant + broken: precommit_fix already runs markdownlint in a container, and
  there is no root package.json). Now: checkout -> make -C readmes precommit_fix ->
  capture/upload patch.
- readmes/Dockerfile: node:20.16 -> node:26-slim (aligns with the docusaurus image)
- dependabot.yml: track /readmes (docker) so the markdownlint image's Node version
  is bumped automatically instead of rotting in a workflow input.
