Only supported versions for jetstreamer "2.8.1" has outdated reloader that doesn't work for ARM

[atropos112]

Describe the bug Previously one had ability to run eventbuses on ARM now they can no longer do this because of the limitation imposed on what version is allowed, namely the limitation now is

failed to get jetstream version, err: unsupported version "latest", supported versions: "2.8.1"

Its not actually the jetstreamer at 2.8.1 that doesn't support ARM but the config-reloader that is running outnatsio/nats-server-config-reloader:0.6.3 instead of say natsio/nats-server-config-reloader:0.12.0 which does support ARM.

To Reproduce Steps to reproduce the behavior: Install argo-events with jetstream as eventbus on arm machine.

Expected behavior It to keep on working on ARM.

Screenshots If applicable, add screenshots to help explain your problem.

Environment (please complete the following information):

• Argo-Events at latest version 1.8.0.
• Jetstream (within the eventbus) at 2.8.1

Additional context I was a bit perplexed if this is a bug or a new feature, but given that something worked and now it doesn't suggests to me that its a bug so I went with that.

There is a "container template" in docs https://github.com/argoproj/argo-events/blob/master/api/event-bus.md#containertemplate where I can change some settings for reloader, image tag is not at my disposal sadly.

@atropos112 - you are able to update the images in the configuration - https://github.com/argoproj/argo-events/blob/master/manifests/base/controller-manager/controller-config.yaml.

Oh so there is a workaround!

So my controller-config looks like this

i am using a helm chart from here https://github.com/argoproj/argo-helm/tree/main/charts/argo-events

which turns out has a setting to adjust that config here https://github.com/argoproj/argo-helm/blob/main/charts/argo-events/templates/argo-events-controller/config.yaml so I can work around this. There the defaults for the versions are

    versions:
      - version: "latest"
        natsImage: nats:latest
        metricsExporterImage: natsio/prometheus-nats-exporter:latest
        configReloaderImage: natsio/nats-server-config-reloader:latest
        startCommand: /nats-server

but it seems "latest" version is not allowed so i have no idea where my 0.6.3 comes from

[atropos112]

I have an idea now, they come from me, i am entirely at fault here... I apologise for wasting your time.
