`buildGoModule` and `buildGoPackage` by default inherit the `platforms`
from go. That seems better than explicitly configuring `platforms.all`.
There are also many packages that specify 'linux + darwin' - this is
even suggested in the documentation. We might also want to update those,
but let's do the noncontroversial change first.
also introduce helm-s3, helm-diff, helm-secrets plugin.
You can create a wrapped helm with these plugins via:
myHelm = final.wrapHelm final.kubernetes-helm-unwrapped {
plugins = with final.kubernetes-helmPlugins; [ helm-s3 helm-secrets helm-diff ];
};
Running `helm plugin list` will show you these are available.
