Construct Hub shows languages based on package.json even if they are not published

https://constructs.dev/packages/aws-bootstrap-kit/v/0.6.0?lang=python provides a command for installing the package in Python. But the package is not actually published to PyPI. The reason Construct Hub displays Python availability is because Python appears as a target in https://github.com/awslabs/aws-bootstrap-kit/blob/main/source/aws-bootstrap-kit/package.json#L14.

P.S.: The maintainer plans to publish the Python version soon, so this might not be reproducible once he does.

First confirm whether the issue still reproduces, since the maintainer expected Python publication. Then inspect the Construct Hub logic that derives displayed languages from package metadata, compare it with the linked package.json target and actual PyPI availability, and verify that unpublished targets are not presented as installable for the example package.
