License information inconsistently returned from version endpoint #1027
Description
It looks like some of the version endpoints return license information, while others do not. I noticed this with Go first:
$ http https://packages.ecosyste.ms/api/v1/registries/proxy.golang.org/packages/github.com%2Fspf13%2fcobra/versions/v1.7.0 | jq .licenses
null
$ http https://packages.ecosyste.ms/api/v1/registries/proxy.golang.org/packages/github.com%2Fspf13%2fcobra | jq .licenses
"Apache-2.0"
But i doesn’t seem to affect npm:
$ http https://packages.ecosyste.ms/api/v1/registries/npmjs.org/packages/penplot | jq .licenses
"MIT"
$ http https://packages.ecosyste.ms/api/v1/registries/npmjs.org/packages/penplot/versions/3.0.0 | jq .licenses
"MIT"
But does affect PyPI:
$ http https://packages.ecosyste.ms/api/v1/registries/pypi.org/packages/urllib3/versions/2.3.0 | jq .licenses
null
$ http https://packages.ecosyste.ms/api/v1/registries/pypi.org/packages/urllib3 | jq .licenses
"MIT License"
I'd expected that if the license is known for the package, it would also be known for the versions.
