Subject: [PATCH] Centralize CI on SciML reusable workflows

Convert Runic, SpellCheck, and Downgrade to centralized @v1 callers;
Tests was already a tests.yml@v1 caller. Clean up dependabot.yml.

- FormatCheck.yml: inline fredrikekre/runic-action -> runic.yml@v1
- SpellCheck.yml: inline crate-ci/typos -> spellcheck.yml@v1
- Downgrade.yml: inline -> downgrade.yml@v1 (preserve julia-version 1.10,
  skip Pkg,TOML, and the disabling `if: false`)
- All callers get secrets: "inherit"
- dependabot.yml: drop crate-ci/typos ignore; julia block over "/" only
  (/test has no Project.toml)
