This commit fixes issue #7775 by removing the fromToml function which
is only available in Helm 3.14+. The changes ensure compatibility with
Helm 3.12 and later versions.
Changes:
- Removed fromToml function from security-configmap.yaml
- Simplified JWT key generation to use randAlphaNum directly
- Updated Chart.yaml to specify minimum kubeVersion (1.25.0-0)
- Added Prerequisites section to README.md documenting version requirements
- Enhanced helm_ci.yml with additional security configuration tests
