frontend: enable stable tagging (#2378)

## Why?

#2332

This issue has been resolved, so we can re-enable stable tagging for the
frontend. The change lets us use our CI/CD pipeline to deliver updates
to the frontend and quickstart-vdk with sufficient release confidence.

## What?

Enable stable tagging for the frontend docker image. This lets us
deliver updates for the
frontend as part of quickstart-vdk.

Note: The stable tag is pulled each time quickstart-vdk is restarted and
the helm chart it uses re-deployed

## How was this tested?

The stable tagging job ran as part of the CI before, we just didn't have
sufficient testing around
the frontend image, so we disabled it. We use the same script for
tagging with latest, so
it should be fine.

## What kind of change is this?

Feature/non-breaking
