Helm3 upgrade section references non-working auto-deploy-image

Description

The Helm3 Upgrade Section references the v2.0.0-beta.1 version of the auto-deploy image.

This version no longer works as it is referencing the old URL to the stable Helm Chart repository, making jobs fail with:

$ auto-deploy download_chart
Download is skipped. The bundled chart in user's repository will be used.
Error: looks like "https://kubernetes-charts.storage.googleapis.com/" is not a valid chart repository or cannot be reached: failed to fetch https://kubernetes-charts.storage.googleapis.com/index.yaml : 403 Forbidden

Updating image to v2.0.0 resolves the problem. Latest version of auto-deploy-image seems to be v2.9.0, but have not tried that one.
