Sets up Renovate as the dependency-update tool for this repository, part of an org-wide rollout.

Depending on this repo's starting state, this PR does some of the following:

  • adds a repo-local renovate.json extending the Contentful shared preset
  • for repos that used Dependabot: ports repo-specific behavior (PR limits, ignores, grouping) into local packageRules where still needed, and removes Dependabot-only automation and secret policies
  • updates docs that referenced Dependabot

Manual follow-up (not handled by this PR):

  • close stale Dependabot PRs and branches once Renovate is active (for repos that used Dependabot)

Migration Confidence: 🔴 Low

Summary

The migration deleted .github/dependabot.yml, removed the dependabot vault-secrets policy entry, and added renovate.json extending the correct shared preset (local>contentful/renovate-config). However, renovate.json includes additional packageRules that group production and dev dependencies by minor/patch updates — logic that appears to replicate the Dependabot grouping config but was not specified by the migration prompt and may duplicate or conflict with grouping already handled by the shared preset. Per the assessment rules, adding speculative Renovate tuning that nothing justified is a low-confidence trigger. The renovate.json should likely contain only the extends line; the extra packageRules block needs a human to confirm whether the shared preset already covers this behavior or whether these rules are intentionally additive.

Files requiring attention

The following files had edge cases or required judgment during migration and should be reviewed carefully:

  • renovate.json
