[bitnami/kaniko] Add ARM64 (linux/arm64) multi-arch support

[haroonniazi]

Name and Version

bitnami/kaniko

What is the problem this feature will solve?

The Bitnami Kaniko image (public.ecr.aws/bitnami/kaniko) only supports x86_64/amd64 architecture.
When pulled on ARM64 runners (e.g., AWS Graviton), it fails with:
"no matching manifest for linux/arm64/v8 in the manifest list entries."

What is the feature you are proposing to solve the problem?

public.ecr.aws/bitnami/kaniko should publish multi-arch manifests including linux/arm64,
similar to how other Bitnami images support multiple architectures.

Adding ARM64 multi-arch support to the Bitnami Kaniko image would provide a maintained,
version-pinnable alternative for teams building ARM64 container images in CI/CD pipelines.

What alternatives have you considered?

Using gcr.io/kaniko-project/executor:debug for ARM builds, which is a rolling tag
from an archived project with no version pinning available.

That was a business decision: while Bitnami containers are multi-architecture, only AMD images are currently published in the AWS Gallery registry. There are no plans to release ARM images there in the short term, but any future changes will be announced and communicated.
