As noted in #788, working with buildpacks that still have
[[stacks]]inbuildpack.tomlcan cause some trouble. While[[stacks]]is deprecated in Buildpack API 0.10, it is still supported: https://github.com/buildpacks/spec/blob/buildpack/v0.10/buildpack.md#buildpacktoml-toml-stacks-array.This PR re-introduces support for serializing a
buildpack.tomlwith[[stacks]]in it. However,Stackremains unused within libcnb, and thus the validation and parsing is weaker. I would expectStackto be removed again in Buildpack API 0.11. This change is mostly to facilitate upgrades.
