What
Pin all GitHub Actions references to full commit SHAs (with trailing
# <version>comments) and enable Dependabot for thegithub-actionsecosystem.Ref: G-Research/gr-oss#1358
Why
A mutable
@vNref can be silently rewritten upstream or by a compromised account and is picked up immediately by every workflow run. Pinning to an immutable commit SHA closes that supply-chain risk; the trailing# <version>comment keeps the pin human-readable. Dependabot is enabled so the pins are kept up to date automatically.Notes
