hubDevs 1.2.0

• New use_hubdev_codeql() switches CodeQL code scanning on a package's GitHub
  repository to the extended query suite, which also flags actions that are
  not pinned to a commit SHA (#76).
• New use_hubdev_dependabot() and use_hubdev_codeowners() create the
  hubverse package .github/dependabot.yml and .github/CODEOWNERS.
  create_hubdev_pkg() now adds both to new packages (#33).
• use_hubdev_github_action() and use_hubdev_pkgdown_action() download
  workflows from the latest hubverse-org/hubverse-developer-actions release
  instead of its main branch. New ref and overwrite arguments select
  another tag, branch or commit and replace an existing workflow without asking
  (#33).
• Remove orphaned, stale inst/templates/pkgdown-netlify-preview.yaml. The
  single source of truth is the remote copy in
  hubverse-org/hubverse-developer-actions, fetched at runtime by
  use_hubdev_pkgdown_action() (#61).
