ARM64 Compatible Builder

[a1flecke]

Please release ARM64 compatible versions of the builder. Currently, when trying to build ARM
with the following command

pack build --verbose --timestamps pack-bug \
  --platform linux/arm64 \
  --builder paketobuildpacks/builder-jammy-tiny \
  --verbose \
  --env BP_JVM_VERSION=21 \
  --env BP_MAVEN_BUILD_ARGUMENTS="-Dmaven.test.skip=true --no-transfer-progress package --batch-mode" \
  --env BP_MAVEN_BUILT_ARTIFACT=target/

we receive the following error:

Describe the Enhancement

Currently, the builder is only released as an AMD64 docker image. Please release an ARM64 compatible version

Possible Solution

Update the Github workflow to release multi-arch docker images using BuildX. The actual build and runner images already do this.

Motivation

We are exploring switching to using AWS Graviton services for our ECS services to reduce cost. We are currently using Paketo buildpacks for building our docker images and would like to continue to do so. We hit this bug while exploring how easy ARM builds would be.
