Bug: Default Helm version v3.18.4 is not applied when no version input is provided; v4.0.1 is installed instead

[serdardalgic]

What happened?

When I use the action without specifying a version

      - name: Setup Helm
        uses: azure/setup-helm@v4

It installs v4.0.1, which breaks workflows that depend on Helm v3.x.

According to both the documentation and the codebase, the default version should be v3.18.4. However, this value is not respected.

Please ensure the correct default version is installed (v3.18.4), or update the code/documentation if the default is no longer intended.

Version
