helm-secrets: Running on Windows fails

Current Behavior

When I install the plugin using Helm on Windows (using a MINGW terminal) and I attempt to run my helm command, there’s an error as follows:

Error: fork/exec C:\Users\MY_USER\AppData\Roaming\helm\plugins\helm-secrets\scripts\run.sh: %1 is not a valid Win32 application.

My Helm command after installing the plugin was something like:

helm upgrade --install some-release --namespace=whatever -f my-values.yaml -f secrets://secrets.yaml chart --version="x.y.z" --dry-run

Unfortunately the command terminates with the error message mentioned at the beginning.

To install the plugin I used:

helm plugin install https://github.com/jkroepke/helm-secrets --version v3.13.0

I even tried the manual way like:

curl -LsSf https://github.com/jkroepke/helm-secrets/releases/latest/download/helm-secrets.tar.gz | tar -C "/c/Users/MY_USER/AppData/Roaming/helm/plugins" -xzf-

In both cases the installation seemed successfull and I could validate the plugin using e.g.:

$ helm plugin list
NAME    VERSION DESCRIPTION
secrets 3.13.0  This plugin provides secrets values encryption for Helm charts secure storing

Expected Behavior

The plugin would work as expected!
