Describe the bug

From the v3.1.0-rc3 "execute helm template command" fails with error:
Error: invalid kube version '1.28+': Invalid Semantic Version
Related change is there ea97dec
Related PR #22650

According to the helm docs, they use this lib to parse semantic versions, but it does not support the trailing +

To Reproduce

• Deploy the ArgoCD onto k8s cluster
• Create an ApplicationSet with helm chart
• Push ApplicationSet into the repo
• Sync ArgoCD

Expected behavior

The helm template command must execute successfully.
