Document workflow for arm64 architectures #367
Description
Problem
In paketo-buildpacks/stacks#51 we see users of paketo buildpacks trying to use buildpacks on the arm64 architecture (e.g. apple's M1 processors). They are encountering issues.
It seems possible to get buildpacks working when running docker under Rosetta emulation, so we should document that. Additionally, we should document that is it not possible to take the OCI image that was generated under emulation and load it into a container runtime running outside of emulation.
Additionally, we may want to link to this new documentation from the Java page, as many of the users on that thread came to paketo-buildpacks from the Spring boot ecosystem.
