Include dependency values in documentation (#275)

I have added a flag to the helm-docs script to include the documentation
for dependencies.

This will add more complete documentation to
https://artifacthub.io/packages/helm/spiffe/spire#values so it is easier
for our users to get started and having a complete overview.
