What this PR does / why we need it:

The semver validation is not compatible with what k8s itself uses.
Here is an example of the version response from the kube api:

kubectl version --output json | jq '.serverVersion'
{
  "major": "1",
  "minor": "28+",
  "gitVersion": "v1.28.15-eks-4096722",
  "gitCommit": "79964c34fd537f50bf77579c5bd51cb4426ae5e7",
  "gitTreeState": "clean",
  "buildDate": "2025-04-19T08:21:43Z",
  "goVersion": "go1.23.6",
  "compiler": "gc",
  "platform": "linux/arm64"
}

The version is compiled as 1.28+. This type of version format is used by AWS EKS and considered valid according to the version validator in k8s.

When the same version is parsed into helm template of helm lint, it is being validated with ParseKubeVersion which uses the github.com/Masterminds/semver/v3 package.

The Masterminds/semver package does not support trailing + symbol and upon command run, it throws the Invalid Semantic Version error.

`helm template . --name-template <APP_NAME> --namespace <NAMESPACE> --kube-version 1.28+ --values <TEMP_DIR_1>/values.yaml --values <TEMP_DIR_2> <api versions removed> --include-crds`
failed exit status 1: Error: invalid kube version '1.28+': Invalid Semantic Version

Adresses the #31063
