Unable to run IntegrationSinks on arm64 machines

[darkgnotic]

Describe the bug

When IntegrationSinks are run on an arm64 machine (e.g. AWS Graviton), they fail to start up with the following error:

"log": "exec /opt/jboss/container/java/run/run-java.sh: exec format error",

Is it possible that the mapping of eventing-integrations-images only contains images built for amd64?

Expected behavior

IntegrationSinks should work on arm64 machines

To Reproduce

• Create a NodePool containing Graviton machines.
• Deploy any IntegrationSink

Knative release version

v0.19.0

Additional context

[darkgnotic]

Alternatively (assuming the container image is from knative-extensions and is built off of the amd64 registry.access.redhat.com/ubi9/openjdk-21-runtime), I suppose you could add a nodeSelector to the IntegrationSink's podspec templates to specify that the pods require the label kubernetes.io/arch=amd64

I guess this is, because we don't set the target platform via quarkus.jib.platform for the quarkus builds eventing-integrations and thus it defaults to amd64.

@darkgnotic In a different repo we set the jib to a couple platforms, see:
https://github.com/knative-extensions/eventing-kafka-broker/blob/60ae6aa1e5234455b19fea3e1e7e50334a93a9e8/data-plane/pom.xml#L453-L481

I think we can do same/similar on the repo for the eventing-integrations for setting this up.

Wanna work on this?
