fix: update renovate rules

[workos-sdk-automation]

Summary

Updates Renovate configuration to reduce noise and improve dependency management:

• Monthly schedule: Runs on the third Tuesday of the month before 12pm UTC
• Conflict-only rebasing: Only rebases PRs when they have conflicts
• Grouped minor/patch with automerge: Minor and patch updates are grouped together and automerged
• Separate major/digest PRs without automerge: Major and digest updates get their own PRs and require manual review

This aligns with the configuration in workos-node#1495.

Greptile Summary

Added a new root-level Renovate configuration to reduce dependency update noise and improve automation. The config implements a monthly schedule (third Tuesday before 12pm UTC), conflict-only rebasing, and groups minor/patch updates with automerge enabled, while keeping major and digest updates separate for manual review.

Key changes:

• Monthly dependency update schedule to reduce PR frequency
• Minor and patch updates grouped and automerged together
• Major and digest updates require manual review
• Rebasing only occurs when PRs have conflicts

Note: This PR creates a root-level renovate.json while .github/renovate.json still exists. The root-level file will take precedence, but consider removing the old .github/renovate.json file to avoid potential confusion.

Confidence Score: 4/5

• This PR is safe to merge with minimal risk as it only updates dependency management configuration
• The configuration changes are straightforward and align with established patterns from workos-node. The Renovate config syntax is valid and follows best practices. Score is 4 instead of 5 due to the potential confusion from having both root-level and .github/ Renovate configs, though the root-level will take precedence
• No files require special attention - this is a simple configuration addition

This creates a root-level renovate.json while .github/renovate.json already exists. Root-level configs take precedence, but having both files is confusing. Consider removing .github/renovate.json to avoid confusion about which config is active.
