Removing unsupported entry

[dlion]

I'm working on a tutorial using the samples and running the detector providing some buildpacks I get an error on the hello-moon one about the version key in the detector file. The platform_api version I'm using is:

❯ echo $CNB_PLATFORM_API
0.12

this is the output:

❯ $CNB_LIFECYCLE_PATH/detector -log-level debug -layers="./layers" -order="./order.toml" -buildpacks="./buildpacks" -app apps/bash-script

ERROR: No buildpack groups passed detection.

No new files have been generated.

Removing that line from the detector I get:

and the plan.toml and group.toml files are there as expected.
