external-secrets release v2.11.1

Fixed

• The helm.sh/chart label is valid for long chart versions: the 63-character cut trims the whole trailing run of -, . and _.

Changed

• Fix broken documentation links in the README and recommend installing via Flux HelmRelease, keeping the legacy App CR as fallback.
• Update README examples to chart version 2.11.0, kubectl gs deploy chart, and remove the legacy App CR example.
