ci: run renovate config validator from the pinned docker image - #143
Merged
Conversation
**Problem:** The validate workflow installed renovate from npm at CI time via `npx`, so a fresh package tree was resolved and downloaded on every run. **Solution:** Run `renovate-config-validator` from the official renovate image, pinned by tag and digest, as a docker step. The version is fixed by an immutable digest, and Renovate keeps the tag+digest updated. Drops the now unused `setup-node` step and the `RENOVATE_VERSION`/`LOG_LEVEL` env. --- _Testing:_ Run in CI
