Add support for stack paketobuildpacks/builder:tiny to sample buildpacks

[ciberkleid]

Getting the following error:

pack build hello-java-img --buildpack from=builder --buildpack ../buildpack-samples/buildpacks/hello-world
ERROR: failed to build: validating stack mixins: buildpack samples/hello-world@0.0.1 does not support stack io.paketo.stacks.tiny

Using a simple Java app to test. The same app without the sample builder builds successfully with the tiny stack.

Can the samples be updated to support the tiny stack please?

We're working on removing the concept of stacks. In the meantime, we could set the hello-world buildpack to work with any stack i.e. *. Let me try this out.

That would be great - thank you!
