Subject: [PATCH] Canonical CI cleanup: TagBot thin-caller + downgrade-caller
 cleanup

- Replace inlined JuliaRegistries/TagBot with the canonical SciML thin caller
  (SciML/.github/.github/workflows/tagbot.yml@v1).
- Downgrade caller: drop the hand-listed `skip:` stdlibs (Pkg, TOML are
  auto-populated by the centralized workflow) and pin julia-version to "lts".
