📝 Walkthrough

Walkthrough

This PR updates the renovate.json configuration to migrate the Helm chart custom manager from regex-based matching to JSONata-based matching. The new configuration extracts chart names and registry URLs using JSONata expressions and adds version normalization via an extractVersion pattern.

Changes

Helm chart custom manager JSONata migration

Layer / File(s)	Summary
Helm chart custom manager JSONata configuration renovate.json	The helmChart custom manager switches from regex-based customType to jsonata customType with new matchStrings expressions that extract depName from access.helmChart, currentValue from split fields, and registryUrl from access.helmRepository. An extractVersion pattern is added to strip leading v from version strings.

Poem

🐰 A config of Helm takes a JSONata turn,
Regex laid aside, new patterns we learn,
Version strings trimmed of their leading 'v' grace,
Registry URLs find their rightful place! 🎯
