Migrate from bitnamicharts/valkey (and bitnamicharts/valkey-cluster) to the official Valkey Helm chart (https://valkey.io/valkey-helm, v0.10.0). Changes: - Remove valkey-cluster dependency and all related values, templates, and unit tests - Update valkey dependency to use https://valkey.io/valkey-helm - Adapt _helpers.tpl (valkey.dns, valkey.port, valkey.servicename) to the new chart's service naming and value structure - Update values.yaml to match the new chart's configuration schema (auth.aclUsers instead of global.valkey.password, service.port instead of primary.service.ports.valkey, dataStorage instead of primary.persistence) - Update all affected unit tests - Update README documentation BREAKING CHANGE: valkey-cluster support has been removed. Users previously relying on valkey-cluster must migrate to standalone valkey or an external Redis-compatible service. The valkey values structure has changed: `valkey.global.valkey.password` is now `valkey.auth.aclUsers.default.password`, and `valkey.primary.service.ports.valkey` is now `valkey.service.port`. --------- Co-authored-by: rishub <183523+rishub@noreply.gitea.com> Co-authored-by: rishub <itsrishub@gmail.com> Reviewed-on: https://gitea.com/gitea/helm-gitea/pulls/1097 Co-authored-by: Markus Pesch <markus.pesch@cryptic.systems>
