Add license info and github slug to dataset

[LukvonStrom]

Dear bump maintainers,

In this PR which is based on #186, I added the SPDX license identifiers and the clear github slug of the updated dependency and the consuming repository.

In addition I tried to add these changes into the miner as well, but the testsuite kept failing for me, making validation of those changes a bit hard.

I updated the JSON Schema as well.

Best regards,
Lukas

@LukvonStrom thanks for the contributions.

I fixed the problem with the validations.
Now I found that some of the JSON have the license data in different places which makes the validation fail.

The licenseInfo and githubRepoSlug fields are required but are missing or misplaced.

Can you verify that information?

This has been fixed now, I also added assertions to make sure this is constantly ensured. Apologies for the initial, somewhat naive implementation :)
