Pin third-party actions to commit SHAs - #13

Centralising the release job here also centralises its supply-chain posture: codama#1149 had pinned changesets/action and pnpm/action-setup in its inline job, which the shared workflow replaced with mutable tags. Pin them in every workflow (third-party only, actions/* stay on tags, as in codama#1149) and add a github-actions Dependabot ecosystem so the pins do not rot. changesets/action moves to v2.1.2 (patch fixes only).

This PR pins the third-party actions used by the reusable workflows to commit SHAs and adds a
github-actionsDependabot ecosystem so the pins do not rot.Centralising the release job here also centralises its supply-chain posture: codama-idl/codama#1149 had SHA-pinned
changesets/actionandpnpm/action-setupin codama's inline release job, and the switch to the shared workflow (codama-idl/codama#1155) would silently replace those with mutable tags. Pinning here fixes that once for every calling repository.pnpm/action-setup@ea17c68d… # v6.1.0andchangesets/action@ae32849d… # v2.1.2inrelease.yml,cut.yml,promote.yml(SHAs verified against the tag objects; identical to what Dependabot already applied on codamamain).changesets/actionmoves from 2.1.1 to 2.1.2, patch fixes only.actions/*stay on tags, same rule as #1149..github/dependabot.yml: weeklygithub-actionsupdates, 7-day cooldown, minor/patch grouped, majors separate (same configuration as codama).Callers keep
