Update de-client pip install to use latest version #28
Description
Because the pip install of de-client doesn't have the --upgrade flag, if the packages is already installed the script proceeds. In the case where a customer is reusing the runner, de-client may already be in the environment. If the customer needs to upgrade to a new version, they can add the de_client_version but if they really just want the latest version, this isn't ideal because then they need to increment this pin.
